Having contributed to your HSA through work, enter amounts shown in box 12 of your W-2 into box 12 of TurboTax's W-2 form, nowhere else in TurboTax. TurboTax will automatically transfer to Form 8889 line 9 the amount identified with code W. Never make entries into TurboTax from your paystubs.
Forms 1099-SA report distributions not contributions. If you made no distributions from the HSA in 2023, you'll have no Form 1099-SA to enter.
