How does TurboTax calculate "points paid on purchase of principal residence" for my deduction? Can I see their calculation for "total 1098 interest and points?

I get that I paid more interest last year than I can deduct on my tax return (only a percentage, $750000 / <mortgage principal balance> ). But I haven't been able to find the formula for how they are calculating my default adjustment number. It appears to take into account the amount of interest I paid, but not the points I paid.
