Actually, I think I finally did something that resolved my issue.  I'm responding here for anyone else that might need to fix this issue for themselves.

I also have 2023 QBDT on my computer.  Once I went in and did the update there, clicked on 21, 22, & 23 to run as administrator. Updated each year to the most current update by resetting the update to get them all, I was finally able to make adjustments in the 2021 file that I needed to and also in the 2022 file that makes changes that I can send back to my client.   whew!!  What an ordeal.  I don't understand why 2023 was the thing that everything revolved around to make it work.
