A tax return that includes a Form W-2 with code Z in box 12 can only be completed with the CD/download version of TurboTax and the tax return must be mailed. It cannot be e-filed. To complete the tax return you must calculate the penalty yourself (you might require professional assistance with this calculation) and in Forms mode enter this penalty on 2022 Schedule 2 line 17h. Absent this entry, your tax return is incomplete.
