Deductions & credits

Thank you! Box 2 appears to have the balance at origination, not as of 12/31/24.

Below that is a section marked "Principal Reconciliation" that shows the ending balance.

 

I think for purposes of a interest deduction I need to consider average balance (=beginning + ending / 2). So I need to input both, right? Or just put balance at 12/31/24 as the box 2 number and call it a day?
