Hello, I'm running into the same problem.
I followed the instructions from - https://ttlc.intuit.com/turbotax-support/en-us/help-article/import-export-data-files/handle-multiple...
I entered my first 1098. My refund was about $23K.
Then I entered my second 1098 from the refinancing. My refund reduced to about $14K.
How's that possible?
I'm using the online version. Loan amount over $750K
Thanks!
