"Box 20 code z has been selected but no Section 199A income has been entered on Statement A"

I've seen other references to this error/issue in prior years, but I can't seem to use the recommendations of leaving the box blank for example to get around it in 2024. 

I have section 199A information, other code z. I get this error on checking, and if I double click my amount (-15224), then I can enter the individual components that are on my detailed 199A document. Great, so I enter all those which still totals the (-15224), but I still get the same error. Everything is entered! How do I get around this?
