When claiming a home office deduction in TurboTax and doing the "actual expenses" method, I am entering my mortgage information. I do have excess mortgage interest (loan amount is over the mortgage deduction limit). On the entire-home "Excess mortgage interest" page, TurboTax says, "If you have excess mortgage interest and it's included in the $[interest paid per 1098] (entire home) mortgage interest reported for this home office, enter 0."
I don't understand what TurboTax means by "included" here. The amount listed in my 1098 is the entire interest I paid for the year (which by definition includes the deductible mortgage interest amount plus the excess interest amount). So does that mean it's "included" and I should enter 0 on this page? (The reason I'm confused is that if I'm right about that, then I don't understand in what situation it *wouldn't* have been "included".)
Thanks so much for your help ahead of time!
