After you file

I entered 0 for the old lender for balance as of 01/01/2019 and the balance for new lender as of 01/01/2018 same as the old lender from old lender's 1098. The federal taxes look fine but this information is being used in CA return and its taking as two loans and summing up the average loan balance from both and using it to calculate my adjusted mortgage interest rate and its coming to a huge negative number . Anyone else faced this issue? How did you fix it? what are you supposed to enter?
