Yes.
You can deduct interest you pay on a loan secured by your main home (where you ordinarily live most of the time) and a second home. Both your main and/or second home can be a mobile home, house trailer, recreational vehicle, or houseboat that has sleeping, cooking and toilet facilities.
Even if you don’t have a 1098, you’ll still need to enter the requested information from an alternate source, such as your mortgage lender or year-end mortgage statement. In that case, just enter everything when prompted as though you have a 1098. (Because you’ll be entering the equivalent of the amounts from the different numbered boxes of the 1098 without actually having that form).
To deduct the interest, follow this path in TurboTax:
Click on Federal Taxes TAB
Click on the Deductions and Credits SubTAB.
Choose the option "I'll choose what I work on".
Find the section labeled "Your Home".
Click start or update on the line labeled Mortgage Interest, Refinancing, and Insurance.
Answer yes to the question of whether you have a home loan, or add another mortgage.
Enter the lender name and hit continue.
On the screen labeled "Tell Us More About Your Loan from your lender", check the option "I did not receive a 1098" and hit continue.
Enter the interest on the subsequent screens.
