You can create a 2019 tax return and do everything EXCEPT print or efile the return and there is no cost. Try recreating the 2019 return as filed, so that you can get used to the software. You can "Check Return" and view the forms, for no charge.

Possibly after doing that you can then create the prior year. If that fails you will need to contact support. In the BLUE left column there is Live Chat when they are available.
