Sorry for reviving this old post - I think I have the same error and I can't efile due to "Box 20 Code Z has been selected but no Section 199A income has been entered on Statement A". I'm using TT Premier Windows version.
Basically smart check complains about no 199a income has been entered even if I entered all the information; I tried step by step and using the form method, I also tried entering a random amount for the Line 20 code Z, but I can't pass the screen.
I wonder if anyone has found a workaround for this issue?
Thanks,
Yiming
