I have updated my QB's Mac software:  "QuickBooks 19.1.16.1140 R17.3 is currently the newest version available." But when I try to create my 1099s, it says it's for "Tax Year 2022". 

After printing the resulting 1099-MISCs, it seems that the figures are correct for the 2023 tax year, inspire of the screen saying "Tax Year 2022". So my problem is solved, but lots of other users are probably experiencing the same APPARENT problem.
