Hi there, @Del3.
Thanks for joining us here in the Community. Allow me to help share some insight about printing out W-2 forms for 2019.
Currently, the option to print W-2 forms for 2019 in QuickBooks is unavailable. Generally, new annual forms like W-2s are delivered with the payroll update distribute in the mid-December.
That's why when you try to access the form you get a warning message. Forms are generally unavailable due to updates to ensure their accuracy and QuickBooks works diligently to provide them as soon as possible.

That should get you back on track. Please let me know if there's anything else I can help out with payroll. I'll be happy to help you out. Wishing you and your business success.
