Somehow your mortgage interest got in there twice. Go to Deductions & Credits > Your Home > Mortgage Interest, Refinancing, and Insurance (Form 1098) and try editing your entry or deleting the duplicate 1098.
If that fails, then:
In the top menu, click My Account, then
Delete a Form (within Other Helpful Links)
Select Delete next to form 1098 or mortgage interest, then reenter if needed.
