After you file

@Lorob1  You added on to a very old thread.  3 years old.  What worked back then to install 2020 will not work now.  You won’t be able to reinstall 2020 or prior.  They only support the last 3 years.  And the License Code started in 2019.  So 2019 and newer needs to connect to Turbo Tax to verify the License Code.  But they have stopped supporting 2020 and prior.  So you can’t activate 2019 and each year going forward.  You can’t activate 2020 or update it or download any state programs.
