It's not saving my mortgage insurance data. How do I get it to save? I've tried to log out and log back in again and it did not work.

If you are entering an MIP (Mortgage Insurance Premium) from your form 1098, are the other amounts saving properly?

You can deduct your MIP, provided you itemize and the insurance contract was issued after 2006. Once your adjusted gross income (AGI) exceeds $100,000 ($50,000 for married filing separately) the deduction is reduced. If your AGI surpasses $109,000 ($54,500 if married filing separately) the PMI/MIP deduction is eliminated altogether.

Once you pay for your return, you can Save/View/Print your return with all the worksheets to review how this was calculated for you.
