I assumed both loans qualify for mortgage interest deduction (secured loan on main or second home).
I just entered two 1098's with identical information except for the lender's name. I used Test 1 and Test 2 for the lender names. Turbo Tax detected possible duplicate 1098 information for my review. I pressed on and both were accepted without error.
Is the amount of each mortgage over $375,000? If so, the combined balance will over $750,000 and you will see a limitation.
