I bought a home for my personal residence this year and rented out one room to a friend at fair market rate the entire time I've lived in the home. I'm following instructions for deducting a proportion of my mortgage interest and property taxes in schedule E (based on rental percentage of 33%, renting one out of three rooms), but I have also deducted the full mortgage interest and property tax amounts in schedule A. Turbo tax is not adjusting schedule A deductions based on anything I'm entering in schedule E. Is this correct? The current set up gives me a better return, but I'm concerned that I'm 'double counting' deductions for mortage interest and taxes as they are occuring in more than one place.
