I’m using the desktop version I got from Costco on my Mac. I did actually type in both 1098 forms. Both are indicated as secured. First is the primary and the other is a secondary (this is the one that isn’t being added to the mortgage interest deduction total). The loans are both refinanced, but back in 2020. The second home is actually my parents house that I am paying the mortgage for. I don’t charge them rent or anything.
