Hi I entered my hsa contribution, but it's not showing up on the summary page where it shows all my Federal deductions? Does anyone know why isn't it showing up? thanks!

The HSA is handled in 3 parts in the TT program :

First the contribution:

Next the limitations screen to confirm you are eligible to make the contributions:

Until you complete the HSA portion of the TurboTax interview to establish your eligibility for an HSA contribution, TurboTax will treat the amount entered on the W-2 form as an excess HSA contribution.

And lastly any distribution:

If it was on the W-2 box 12 code W then it will not show up on that deduction summary screen because it was already deducted from your wages.
