I am having the same issue. I guess the only option is to do what you said:
Nothing seems to work other than change the origination date (which for the refinance was in 2020) to the origination date of the original loan. This however would cause a discrepancy in the 1098 reported to the IRS.
And then if you get audited, write a letter of explanation to the IRS about Turbo Tax's error in the software.
It's not fun having to fudge data on your tax return to compensate for Turbo Tax's failures.
