Box 7 on Form 1098 states: "If address of property securing mortgage is the same as PAYER’S/BORROWER’S address, check the box, or enter the address or description in box 8."
If box 7 is checked, Box 8 does NOT have to be filled in. Further on in the interview, TurboTax will ask Is this loan secured by a property of yours?
If box 7 is not checked, the mortgage interest you entered may not be deductible, and could cause your refund to go down.
