If you made an excess contribution to your HSA, then you must withdraw the excess.
If the 2020 HSA contribution exceeds the allowable amount, the excess must be withdrawn by May 17, 2021 to avoid a penalty (October 15 if you filed an extension).
Form 5329 is created only when you did not withdraw the excess contribution before the due date of the return.
Normally, when TurboTax tells you about the excess contribution and you tell TurboTax that you will remove it, the excess is added to Other Income (so it is taxed) and that is the end of it - no 5329.
You get 5239 only when you tell TurboTax that you did NOT intend to withdraw the excess by the due date of the return.
NOTE: if you withdrew the excess before the due date of the return last year, then when TurboTax asks you this year if you overfunded the HSA last year, answer NO. When you withdrew the excess, you "cured" it. TurboTax should really ask "Did you carry over any excess HSA contributions from last year to this year?"
