Hello @mamj.

Thanks for checking in with the Community for information about 3 up NEC forms.  Those are available in QB Desktop 2019.

I see that you’ve run the updates, let’s try that one more time.

When you’re updating to the most current release for QuickBooks Desktop, please make sure to enable the Reset Update option. It usually fixes issues related to any critical update, as well as other possible errors within the product. In case you need the steps, here's how:

• Click the Help tab at the top menu bar and select Update QuickBooks Desktop.
• Go to the Update Now tab.
• Put a checkmark on the box beside Reset Update.
• Hit Get Updates. 

Enabling the Reset Update option is critical especially if you’ve run updates recently. Once you’ve updated, I recommend closing QuickBooks and restarting your computer once again.

If you’re still not getting the update, your next step will be to uninstall and reinstall your QuickBooks and try to get the updates again.

That should do it! Let me know if you have any additional questions or if there is anything else I can help with.
