Investors & landlords

My situation is similar, but not exactly, like the ones already listed.  I have a K-1 from a new real estate partnership that bought a piece of property in 2019 but hasn't yet started to do anything with it.  My K-1 has no income, but Box 20 is marked with Z, and STMT is shown instead of a dollar amount.  On the "Section 199A Information Worksheet" attached to the K-1, the only thing listed is $150K in column A for "Qualified Property."  As others have experienced, any combination of entering dollar amounts or not for Box 20 and Z, and regardless of what I seem to put in the detail for the UBIA (or elsewhere), the review says "Box 20 Code Z has been selected but no Section 199A income has been entered on Statement A."  What to do?
