I find myself eating mostly sea salt these days, meaning that I am not getting much, if any, of the iodine supplement in regular salt.
Is this a problem and should I be taking an iodine supplement separately? Where can I find an iodine supplement?

The Goiter Belt
You’re near it.
The good news is, even a basic multivitamin usually contains 100% your RDA of iodine.
Also, I’d rather live near the Goiter Belt than the Kuiper Belt.
Actually, sea salt (and sea plants, and the meat of many sea animals) contains natural iodine.
Iodide was originally added to salt to combat goiter, but now Americans typically eat so much salt in processed foods that we get double the iodine we need, or more. Excessive iodide can apparently be cytotoxic. Notice that this effect occurs in the context of selenium deficiency, which is also mentioned in the “goiter belt” link.
I personally buy non-iodized (“plain”) table salt for general use at home, because I know that most of the salt I get in processed or prepared foods is going to be iodized.
If anything, I would look at a selenium supplement before an iodine supplement.
When my blood pressure started creeping up and I started eating low-sodium style, I asked my doctor about getting enough iodine and if I should supplement it, and he didn’t think that would be a bad idea (I don’t take a mulit-vitamin because they all make me nauseated).
ETA: I got an iodine supplement from a naturopathic doctor - I imagine you could find it at any health food store. It’s just a couple of drops in a glass of water - it doesn’t taste great, because it’s iodine. 
Not so. It is NaCl as pure as possible, with minor anti-caking agents added. Rock or Sea, it it identical for all practical purposes. It also tastes the same. You can have either iodized.
Some Sea salt has crystals like Kosher salt, which have a different mouth feel, so it can “taste” different when not dissolved. Once dissolved it tastes identical. In some very delicately flavored dishes some dudes claim they can taste the Iodine. But again, both rock and sea salt can be iodized or not iodized. The label will tell you.
Fleur de sel or Gray Salt (and variations) is expensive and not refined. It likely has a trace amount of iodine in it. It does have a slightly different taste, but then again, it’s not pure NaCl.
Kelp contains Iodine, and thus sushi with Kombu should be a good source.

No it does not. That is the constiuents of raw, unrefined Sea salt. Much like Fleur De Sal. You do not eat raw sea salt.
*Unrefined salt
Main articles: Sea salt, Halite, and Fleur de sel
Different natural salts have different mineralities, giving each one a unique flavor. Fleur de sel, natural sea salt harvested by hand, has a unique flavor varying from region to region. In traditional Korean cuisine, so-called [Jukyeom| “bamboo salt”]] is prepared by roasting salt [13] in a bamboo container plugged with mud at both ends. This product absorbs minerals from the bamboo and the mud, and has been shown to increase the anticlastogenic and antimutagenic properties of doenjang.[14]
Completely raw sea salt is bitter because of magnesium and calcium compounds, and thus is rarely eaten. The refined salt industry cites scientific studies saying that raw sea and rock salts do not contain enough iodine salts to prevent iodine deficiency diseases.[15]…
Refined salt, which is most widely used presently, is mainly sodium chloride.

Almost all salt used for eating is* refined.* Thus Sea or Rock makes no significant difference.
I did mention the rare and very expensive unrefined Salts.
I once made some sea salt. I picked up a large rock from the dead sea, dissolved in water, filtered it to get rid of particulates, principally sand, and then cooked it down to fine crystals. I gave it to a friend of mine who was into such things. He never mentioned if it any particular flavor.
Thanks, all. I do regularly take a multi-vitamin (I don’t know if it has iodine. Need to look). I’ll probably check with my doctor at some point too.
