Thank you for posting here in the Community, @Cara Dobbins. Let me share some insights about the discontinuation of QuickBooks Desktop 2019.

You cannot access add-on services for QuickBooks Desktop for Windows 2019 after May 31, 2022. It includes QuickBooks Desktop Pro, Premier, and Enterprise Solutions v19 in all versions.

If you don't use QuickBooks Desktop 2019 add-on services, your software will continue to function normally. You won't be able to sign up for live technical support or any other Intuit services that work with QuickBooks Desktop. In addition, discontinued versions will not receive security fixes or updates.

You can check on this article to learn more about the process: QuickBooks Desktop service discontinuation policy and upgrade information.

If you want to upgrade to a newer version of QuickBooks, this article will walk you through the process: Upgrade QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.

You can always leave a comment below if you have follow-up questions with the discontinuation policy or start a new thread if you have any other concerns. I'll be here to lend a hand.
