A late response. I have the exact same situation. We financed a personal mortgage for our son, secured by his home, so no Form 1098. We were not the seller. It baffles me that Turbo Tax has still not developed a screen to accommodate this. The only way for a borrower to say they did not receive a Form 1098 in Turbo Tax is if they check the button saying that the lender was the seller. Since that is not accurate, it seems like the way I will proceed is just as if the borrower did receive a Form 1098. In Turbo Tax, there is no way to do this correctly. Their software does not allow for this situation, which cannot be all that uncommon, to exist.
