Hello there, @jfreedy. 

Yes, as mentioned by my colleague above that the QuickBooks Desktop (QBDT) for Mac 2020 is compatible with the Mac OS version Monterey. Users with compatible Macs will be able to install this update. You will be prompted if your Mac is set to auto-update. You can follow the steps provided by RCV.

You may also refer to this link if you need further assistance when installing and setting up QBDT for Mac: Install and set up QuickBooks Mac Desktop.

In addition, you may check our QBDT Mac articles for your future reference: Help articles for QuickBooks Desktop for Mac.

Just add a post/comment below if you have any other questions about installing QuickBooks, I'll be right here to help you however I can. Have a good day ahead!
