Yes, I was thinking the same thing (need to go line by line).
I think I found the cause: If you go through the math/worksheets to compute Schedule A line 1 (see "Schedule A Line 1 Medical Expenses Worksheet"), they subtract the amount distributed from your HSA (Line 13B of the Worksheet). This leads to reducing the deduction on 1040 Line 12. I suspect I need to go back through medical deductions and see if I can enter the items I used the HSA funds for.
Thanks for letting me know I was not "out in the weeds" thinking HSA distributions used for qualified medical expenses are non-taxable. 😉
