Adj Basis of Tot Inv Ast shouldn't be less than or equal to zero?

TT will not complete the error check without me giving a non zero number here and also a non zero number for foreign investment assets .  this number than seems to go into the form 1116 worksheet.

I have a simple tax return with some mutual funds that generated passive income dividends that had some foreign taxes paid

 

Im re-asking this question because prior answers didnt answer the question
