I don't have a W-2G, only a K-1 from the partnership we created to receive and distribute the winnings (it was an office lottery pool). Possibly a W-2G was issued to the partnership, but I don't have access to that. I entered the K-1 into TT with the amount in line 11, code K (for gambling winnings), and a slightly reduced amount in line 19, code A (for cash distribution). There were also withholding amounts (federal, state, city) in box 20, but that's a separate issue. My main issue is that the amount in line 11 here somehow got propagated to Schedule 1 in both line 8b (correctly) and line 8z (incorrectly), resulting in a line 9 total of twice the amount.
