I rented out a portion of my house (25%) for four months in 2016. Where do I enter interest and taxes on Form 1098? Personal or rental section?

I rented out a portion of my house (25%) for four months in 2016.  In turbotax, how do I apportion the interest and taxes on Form 1098?  Do I manually calculate and enter 25% in one place and 75% in the other?  Or do I enter it all in one place and turbotax figures it out?
