Prorating rental expenses
Bought a house in 2019 and have used, since purchasing it for personal use. Got it in mid-July and have used it for personal use for 168 days. I started renting out a bedroom to a roommate, starting August 1st through December 31st for 153 days.
Turbotax says it's going to prorate real-estate taxes and mortgage interest, but seems to only be prorating based on 153 days out 168 days, but NOT also based on the square footage (the room's 125 square feet and exclusively used by my roommate.
Do I need to manually prorate my real-estate taxes and mortgage interest for the square footage being exclusively used, but TurboTax will do the prorated # of days rented calculation?
Do I need to manually prorate and input all other expenses (supplies, maintenance, etc.) It almost looks like Turbotax is prorating other expenses based upon 153 days (days room rented out) out of 365 days.
Any suggestions on how I should proceed?
