If you can calculate the proper interest, enter it in the program. The actual tax form, Sch A, only shows the total allowed interest. The program does the work with multiple forms and balances over $750,000.
- If your balance was below $750,000 all year, then all of the interest would be deductible if related to the purchase of the home, total it up and enter it. Make one simple entry.
- If your balance was over $750,000, your interest allowed is limited on the federal- probably state. See About Publication 936, Home Mortgage Interest Deduction
