Where to enter my 1098 for my primary home which I rent a room of? in Deduction or in expense?

[MargaretL · Accepted solution]

You should enter 1098 form in both sections.  You should allocate 1098 expenses (mortgage interest, real estate tax, mortgage insurance) between rental room and your house.  You can do so based on the square footage, for example. Then, the rental portion will be entered as your rental expenses, the amount allocated to your house "living area" is entered in the Deductions & Credits section, Your Home category.
