If your software is at the latest release then save your tax return and close the TurboTax program. Re-start your computer. After the computer has re-started open the TurboTax program and see if the form and schedule is now available.
If not, then save the tax return and close the TurboTax program. Uninstall TurboTax and re-install TurboTax. That should clear out any condition preventing the application from updating correctly.
Uninstalling the software does not affect the 2020 tax data file for your tax return. The tax data file is in a different directory than the TurboTax program. It is, by default, in Documents directory TurboTax folder.
