In the < Federal taxes section...………...in the Deductions&Credits sub-tab. Expand the menu there and there is a Your Home section that takes care of that. A line is there for those entries labeled:
"Mortgage Interest and Refinancing (Form 1098)"
Be carful with the Property Taxes.....if they are entered as a part of your Mortgage payments, do not enter them a second time at the "Property (Real Estate) Taxes" menu line. That second entry point is only for folks who no longer have a mortgage, or who pay them outside of their Mortgage.
