I’ve been having a similar issue with a desktop version for a Mac as well.
Uninstalled, cleared library, cleared cache, cleared all TurboTax2021 related files, reinstalled, did that all again with a different copy of TurboTax 2021. After importing the .tax file in order to complete the e-file. TurboTax still crashes leaving several pages of code, including error code: 0x02000148.
