Detroit form 5121 not handled correctly

Turbotax Premier does not handle the City of Detroit form 5121, in particular, Part 3, correctly, for 2023. I believe it has never handled it correctly, at least the past several years. I have to complete it and mail it manually. 

 

Turbotax: can you please acknowledge that my statement is true? If not, please explain how to make it work.

If you confirm that Turbotax does not handle this correctly, can you please let us know whether you intend to fix this perennial problem.
