If you already downloaded to the latest release in the 2021 version and it still doesn't work, try the following:

I was able to make it print 3 part 1099NECs in version 2021 by resetting the update. When you are on the page to do updates and the tab you pick is "update now" , at the bottom just to the left of "get updates", there is a key  that says "reset update" . Press that key and then press "update now" and it will reinstall all of your updates. Then when it's done, close the program (I may have restarted my computer as well) and when you open it all back up it should work. You'll have your first clue when you're going through the wizard and it says the 1099s are due 1/31/22 now instead of 2/1/22 like it was saying. It worked for me so I hope it works for all of you as well. Good luck
