This is a year old post, but this usually happens when a preference of Applications support file has become damaged or corrupt. The solution is to do a total uninstall of ALL associated files the then empty the trash restart the Mac before re-installing.
Corruption could have occurred in the Application or in an associated preference or support file.
The best remedy is to totally uninstall TurboTax and all associate files and then re-install. That will not delete or change any .tax2018 data file that had already been created with the tax data.
To uninstall the application and all associated files need to be deleted and then the application reinstalled. If there was a state then the state must also be reinstalled.
