Get your taxes done using TurboTax

TurboTax will calculate the Rental % and send the balance to Itemized Deductions on Schedule A.

 

This works as expected. The problem I am having is that the balance send to Sch A does not seem to be correctly capped, and I haven't found a way to fix it.

 

If I input another mortgage interest in Deductions and credits section, it would create a duplicate (the portion created by rental property I entered in income section + the one I entered in deductions), and the result would be way off normal.
