I am having a similar problem. I refinanced the loan so I have two 1098 Forms -- the first is interest on the original loan for 9 months that was paid off. The other is the 1098 for the interest on the new loan for 3 months. Turbo Tax is treating these as two loans and adding the old and new loan together! This results in a loan amount and balances twice the size of the actual mortgage. Turbo Tax needs to correct this glitch and recognize that refinance is not two loans but simply a replacement loan. I have had to override the calcualtions to get the correct mortgage balances.
