The same steps as making inactive, but the Edit Client will show Make Active

https://proconnect.intuit.com/community/manage-customers/help/how-to-make-a-client-inactive-in-proco...

on the client list page, on top of the client list, there is a gear button, click on it and check "include inactive clients", then there will be a button showing "make active" for each in-active clients, click that, it will work.

Thank you -- I was close but didn't see the button at top of page!  Thanks again!
