Hello there, BookkeeperNatasha.

QuickBooks Desktop 2019 is still supported until May 31, 2022. After the said date, access to add-on services will be discontinued for QuickBooks Desktop for Windows 2019. This includes all versions of QuickBooks Desktop Pro, Premier, and Enterprise Solutions v19. 

Since you're using an older version, you may want to read through this article to learn more about the discontinuation policy and upgrade information: QuickBooks Desktop service discontinuation (Disco) policy and upgrade information.

If you mean you're unable to print 1099-NEC using QuickBooks Desktop 2019 version, then you'll want to perform the following troubleshooting steps to fix this.
