Whole house expenses are not summing two mortgage interest payments even though two show up and are checked to be included. Cannot get the "summary" to sum to be right.

Looks like an error in the code as total mortgage interest payments should be correct in summary. Their extra interest sections did not seem to be for two simple mortgages that are not huge.

What 'summary' are you referring to?  Is your Mortgage Interest showing correctly on Schedule A? 

If you are claiming your mortgage interest for a Home Office deduction, be sure you indicated that you used the office all year and that 100% of your business income was derived from the office use.

On the 'Summary of Home Office Expenses' page, is the Mortgage Interest amount correct?  If not, go back through the screens where you link your mortgages to your home office.  If two mortgages are listed, you need to Edit each of them.

Verify that the correct amount of Mortgage Interest shows on Form 8829, Expenses for Business Use of the Home, on Line 10. 

Here's more info on the Home Office Deduction.
