The tricky part is that you have to check more than one box on the page "we need more information for your 199A income." Although you have already told TT about income, deductions, you need to check the appropriate boxes and put in numbers you already put in. Oh yes, I thought you (TT) already know it has business income, so why check it again? Ha, you have to so that it will accept your entries on K-1 page about code Z entries.
