Do I enter my 1098 information on my rental portion or deductions & credits?

Generally, if a property has part rental use and part personal use, you would enter the mortgage interest and property tax information in the rental expenses section first. 

The personal portion should be carried automatically to the Schedule A.  You can go to the personal portion and verify that the amount was transferred over.  There will be an amount on the screen in the personal section showing what has already been entered and where it was entered.  Do not duplicate the entry in both places.
