@EarLobe I suggest totally uninstalling the CD instillation and then download the installer file from TurboTax per the following FAQ that contains the latest updates. The original CD version did not play will with Big Sur but the updated version seem to work OK. The problem is getting the CD version to update. So download as if you did not have a CD drive.
