You should not need to uninstall and reinstall TurboTax. Please clarify each of your form 1098 boxes 1, 2, and 3 by posting here. Someone may be able to assist with the TurboTax entries for the correct calculation.
Bottom line is: If you had one primary home mortgage and sold/paid off that home that had a mortgage balance less than 750,000 (375,000 if married filing separately) and subsequently bought another primary/second home with a mortgage balance of less than 750,000 (375,000 if married filing separately) then all of your mortgage interest would be deductible.
