Deductions & credits

Yes, I am having a similar problem with multiple 1098s, combination of 2 dwellings, a refinance, and a change in mortgage servicers.  The system thinks that I am exceeding the 750,000 limit and is restricting the donations.  Please fix this problem quickly!  Also, when I look at the Mortgage interest worksheet, the months are all wrong and it will not allow me to fix them.  Where do you input that information?
