I am having the same problem as several others.  I am able to print the 1096, but not the 1099's (from QuickBooks desktop 2021).  I can go all the way through the wizard, but when I click print 1099's nothing happens.  It doesn't bring up an error or send anything to my printer.  As an accountant preparing 1099's for clients, I have several versions of QuickBooks loaded on my computer.  I am able to print the 1099's in QuickBooks desktop 2020, but not 2021.  With the deadline fast approaching  for these forms, this is very frustrating.
