As Joe Biden would say, "Here's the deal jack..."
Trying to answer your SPECIFIC question, no ratholes please, here is how I SOLVED the problem: There seems to be a disconnect within TT so that Box 7 on your 1098 needs to be checked after all. Somehow within TT an unchecked Box 7 does not then look at Box 8 to confirm your address, hence even if you indicated that the loan was secured by your property, the benefit does not come through.
Said differently, checking Box 7 resulted in my mortgage interest listing correctly in the Home Interest Worksheet, which then listed correctly in Schedule A, which then allowed my deduction to reduce my tax liability. This little Box 7 exercise was not needed for my 2019 taxes, but for some reason the "bug" appeared for 2020.
