The subject of the post implies that you have not yet filed your 2024 tax return. If you requested a filing extension, you have until October 15, 2025 to obtain a return of the excess contribution and avoid the penalty (despite the fact that TurboTax says April 15 when it asks if you will obtain the corrective distribution). Whether or not you obtain the return of contribution affects how you prepare your 2024 tax return. To obtain a return of the contribution, contact the HSA custodian to explicitly request a return of excess contribution.
If the excess contribution was made through your employer, reported with code W in box 12 of your W-2, it seems that you will have no choice but to file your tax return on paper even if you correct the excess contribution because the contribution is still required to be reported on Form 8889 and TurboTax effectively blocks dependents from e-filing Form 8889. However, if the contribution was a personally deposited contribution, a permissible return of excess contribution by October 15, 2025 would mean that no Form 8889 would be included in your tax return when you indicate that you will obtain the corrective distribution (ignoring TurboTax's mistaken implication that the deadline was April 15), so you would avoid the issue that is preventing you from e-filing.
