I am having the same issue.
The question about the loan being sold is only asked on the first 1098 that is entered, not on subsequent ones. So the total from the lender that the loan was sold to is also getting added as being borrowed in 2019. This is definitely a bug in Turbo Tax. If this bug does not get fixed, I may have to go to a CPA (after 15 years of using Turbo Tax).
