Thank you @Carl!!!! I was nervous to type in 54% of the 1098 number in the box, when the instructions say to type the 1098 number in the box and don't mention needing to adjust it outside of TurboTax. But now I know, I just multiply my 1098 number by 54% for the duration of the loan.
I *am* using some of the "extra" 46% to do repairs/upgrades on my primary residence. But I thought those don't count, because it's not a part of my business? (I mean, it's slightly related I suppose - I manage my investment property from my primary residence and therefore my primary residence needs to be maintained in order to serve as an office space...)
