Investors & landlords

When I completed the return and went to review, a missing entry error generated for this entry.  The cell was blank on the worksheet.  I’m trying to understand where this number should be coming from.  I’ve called several times to support and am still unclear how to proceed.  I would think this entry would have been calculated from the imported data from the 2019 return, but apparently it is not and the directions are very unclear.  My question really is, should this have been calculated and if so how do I get that to occur or perhaps Oler move the over ride, and if it is not calculated, where does the number come from in the 2019 return?

 

Thank you!
