I think you miss the point. I started with the 2018 version. On opening of it, TurboTax forced an update to the 2020 version and thus the problem. Reinstalling from disk only gets me back to the same auto-update point.
Where did you get this disk? None of the TurboTax desktop programs, CD or Download, ever require you to get a different tax year when updating the software being installed.
Contact TurboTax support and they may be able to push a 2018 installation file to your download account.
