It was on “The New Twilight Zone” and was adapted from a story by Joe Haldeman, “I of Newton.”
This is a very common trope, so much so much so that Michael Armstrong wrote “Absolutely the Last – This is It, No More – the Final Pact with the Devil Story.” That may have been the one where an author was required to get a particular story published or lose his soul. No editor wanted it, until, just in the nick of time, an editor bought it. For The Last Dangerous Visions 
Others:
Damn Yankees book by George Abbott and Douglass Wallop, Music and lyrics by Richard Adler and Jerry Ross – classic Broadway musical & film. Joe Boyd sells his soul so that the Washington Senators can get into the world series. Songs include “Whatever Lola Wants,” “You’ve Got to Have Heart.”
“The Same to You Doubled” by Robert Sheckley – the devil gives the protagonist a wish, no strings attached: he can have three wishes, but his worst enemy gets each of them doubled.
“Dealer’s Choice,” another New Twilight Zone episode (by that I mean the 1980s version, not the UPN one). Dan Hedaya plays the devil who sits in on a poker game. He always has the highest hand, and eventually challenges M. Emitt Walsh for his soul.
Walsh is dealer, and chooses to play lowball – lowest hand wins.
*For those not in on the joke, Harlan Ellison announced in 1974 that the book would be published “in six months.” We’re still waiting.
