Thank you for being a part of the Community, @billhdz.
Let me share some information on this. QuickBooks Desktop 2019 version was updated a week ago to include the Monterey capability, and Quickbooks 2021 hasn't been updated since June and does not yet include the Monterey capability.
We will make sure to edit the descriptions of products as necessary as updates are made! I hope this helps, and please let me know what else I can help you with. Take care!
