I bought and sold a home in 2019. The sale took longer than expected, and I owned both for a few months. Accordingly, my total debt for 2019 exceeds the 750,000 limit. However, when I enter both 1098's, TurboTax considers *all* my mortgage interest paid in 2019 qualified for deduction, instead of just the interest up to the 750,000 limit. I don't know how to get it to apply the correct multiplier to my mortgage interest paid. I have tried entering and re-entering the 1098's several times.
For desktop versions:
For online versions, after entering the 1098 interest information, continue through the screens and TurboTax will ask you if the interest needs to be limited.
