Deductions & credits

Hello, 

can I ask for assistance on this as well? I have a original home loan dated 2/2017 for $890K and refinanced in 2020 so I got 2 1098s.  I should be getting 100% mortgage interest deduction because it is a “grandfather” which I did get it in 2019. But this year when I entered the 2 1098s separately, Turbo Tax doesn’t give me the full amount.  If I combined both box1 like the instruction says when I entered the data in my original lender screen, I got the 100% deduction. I am not sure whether the limitation in Turbo is set incorrectly when I entered these forms separately? And, should I just add them together? Thanks
