Deductions & credits

I also have an assumption that TurboTax 2019 does not decrease taxable amount by house depreciation value (which was calculated last year).. based on Dynamical 'Federal refund' value in the left upper window tax was calculated not from the rental income, but rather rental income PLUS house depreciated value, which is for me giving almost $1000 difference (so it's hard to miss).

 

How to report a bug, request its verification and fix (if confirmed) before I filed taxes? 

I want to use convenient efile, which allows me to see all forms after they're filed. I don't want to find incorrect calculations after taxes are filed and battle with TurboTax regarding that.

 

Thank you,

Alex
