Yes, @claudettew. Let me guide you along the process of the QuickBooks Desktop discontinuation process.

Though there isn't an update yet for the Desktop 2021 version at this moment. QuickBooks Desktop releases and implements a discontinuation policy every three years, including versions of Desktop Pro, Premier, and Enterprise. 

Nevertheless, it would be better to wait for an announcement and when will this discontinuation process be implemented for version 2021.

I'm adding this page for the complete information on the QuickBooks Desktop discontinuation policy for the 2020 version.

For instance, you need to create a backup file of your company; see this article for the detailed steps: Back up your QuickBooks Desktop company file.

Plus, to ensure the continuity of operations and receive the latest features, you need to upgrade it before the discontinuation end. Visit this article as your reference: Upgrade QuickBooks Desktop Pro, Premier, or Enterprise.

Thanks for coming to this thread, @claudettew. Know that we are always here to assist you. Stay safe.
