Hi there, @Kellyj7364.

I'm here to share some update. 

After May 31, 2023, access to add-on services will be discontinued for QuickBooks Desktop for Windows 2020. This includes all versions of QuickBooks Desktop Pro, Premier, and Enterprise Solutions v20. If you don't use any of the add-on services in QuickBooks Desktop 2020, your product will continue to work for you.

With the discontinuation in 2023, you can still use the app if you have purchased a not subscription-based.

However, there will be no more updates, and you will have to troubleshoot all the issues manually.

You can refer to this link for more information about the discontinuation of the QBDT UK version: QuickBooks Desktop is being discontinued.

I hope your questions are answered. Please touch base with me here for all of your QuickBooks needs, I'm always happy to help.
