I rented a room in my primary residence this year. In the rental income are its asks for mortgage interest isn't that double counting that since its already a deduction?

hi, I rented a room in my primary residence. I'm already claiming mortgage interest/taxes as a deduction on the home but in the rental income area it also asks for interest and taxes on the property. Should I not put it in here since I'm already claiming it as a deduction somewhere else?

When you rent a room in your home, you have to apportion the common expenses such as mortgage interest and property taxes between the personal use and the business use (rental). One common method of determining the business use percentage is to divide the square footage of the rented area by the total square footage of your home.

The business use portion is deducted as an expense in the rental section and the personal use portion is claimed as an itemized deduction in Schedule A - Itemized deductions.
