Deductions & credits

I have the same exact issue (4 1098s for the same mortgage for 2019) and TurboTax has calculated 3 different refund amounts when I used the workarounds here.  I'm VERY concerned that TurboTax is not calculating things correctly.

 

How is it possible that SAME input results in three DIFFERENT results?

 

TurboTax - time to actually provide a meaningful response to this.
