Multiple 1098s due to loan transfer and primary sale
During 2021, I sold my previous primary residence (Prop-A) and acquired a new primary residence (Prop-B). I had a mortgage on Prop-A that was transferred in 2021 (about two months before selling the home). As a result, I received two 1098s for Prop-A. The Prop-A mortgage was under the 750K limit and I owned it for 4 months of 2021. I additionally received a 1098 for Prop-B, which exceeded the 750K limit and was owned as my primary residence for the remaining 8 months of 2021. In total 3 1098s.
To complicate things further (I think, maybe not), the mortgage on Prop-A was refinanced in 2020 and as a result is not the "original loan used to buy the property" as asked in the interview questions in 2021.
How do I go about entering the 3 1098s and how do I ensure that I am able to take a deduction for Prop-B mortgage interest (albeit a reduced amount as it exceeds the 750K limit).
