Ah, thanks for the clarification!
The 4797 Part II income should be entered in the TT K-1 Wks Box 11, Code F, enter the total of Code F items, including your amount. The next screen check Section 751(b) Gain or Loss... and enter the amount you have. Section 751(b) sounds scary but you can ignore that - the amount goes to Form 4797 Part II line 10 and that's what we want.
For the 6251 line 17, that's the K-1 Box
17 (AMT items), Code
B,
Adjusted gain or loss
