Thank you for your reply - I thought after converting I could actually view the 2020 Tax Forms.  I can see the 2020 figures under the check return option (in the 2021 Tax Return Screen) but not in the actual 2020 Form 1040 format - it appears that option is not available unless I recreate the 2020 return.  Converted clients are only showing up in 2021, no clients are listed under 2021.
