I have similar issue, the check flagged missing information for the Z notation in the box20.
The step buy step guide does not have rental income as an option when asking about 199A income.
it has all the other forms but "rental income" is not there.
I was able to find it in the forms K1 in section D1 "Qualified Business Income Deduction - Statement A Informtion"
When I put the information there it was accepted and the rest of the form was filled out correctly.
