I'm curious as to why you are not going through the normal process of entering your mortgage 1098. You need to separate the amount of proceeds from the refinance used for investments (equity debt) from the home acquisition part. The average balance that goes on line 2 of that worksheet will be the average balance of the acquisition part of your mortgage in 2023. Your mortgage premiums are applied to your equity debt first. Turbo Tax will figure this out for you if you go through the mortgage interest deduction process.
