TurboTax Home and Business not counting mortgage deduction

Hi! I need help. We refinanced our mortgage in 2020, and TurboTax is not counting the interest we paid on both the old and new mortgage. The strange think is in the Deductions and Credits page it shows the total amount of the interest we paid two mortgages as a deduction. But in the summary screen you see when you hit 'done with deductions' it is only showing about half of our interest paid. We are missing out on several thousands of dollars in interest. I think I'm putting in the info correctly from 1098 forms from the banks. We paid off the original mortgage and a HELOC totaling about $700k with the new mortgage, that was for $800k. We are using the extra cash for home improvements. I wonder if I'm hitting the cap on mortgage interest ($750k), but that doesn't seem correct. We paid interest on the first mortgage and HELOC from Jan 1 to July 31, and then paid interest on the new mortgage from Aug 1 to Dec 31. Nothing I do seems to fix the error. Any help would be greatly appreciated. Thanks!
