My understanding was that a separate connection was required to be set up--on the "User DSN" tab in the "ODBC Data Source Administrator" portion of Control Panel--for *EACH* combination of year/module that you wanted to have the ability to open.
  So "2020 IND" <> "2020 SCO", and neither of them works for "anything at all in 2019".

Have you set up an additional connection there?
