Investors & landlords

Update:  So I added the 1098 info into the rental expense portion and it assigned a portion of it to the rental expense.  Turbo Tax did not automatically assign the remaining portion into the Federal Taxes area so I did it myself.  Hypothetically, my 1098 says $10,000 in mortgage interest.  I input that into the rental/royalty area and it assigned a portion $6,000 as a rental expense.  Remember, it was almost a half year lived in and the other half year rented out so it was prorated.  The $4000 remainder (I believe) should have been automatically assigned by TurboTax as a federal tax deduction but it was not automatically assigned so I manually input the $4000.  Is this correct?  Thank you
