I was on the phone with TT, and a nice support technician named Mariah gave me another solution.
When the error pops up during Smart Check, it takes you to the Home Mortgage Interest Worksheet.
The error says to enter a number for Line 3. Beginning Balance. But if you click on the box, it won't let
you enter any information.
Solution: Right click on the box where you want to enter the number. From the Pop Up menu, choose Override. (I think there's a second "Yes I want to Override" window.) I was then able to enter the Beginning Balance.
Hope this can help others. Cheers
