Hi bruce6,

Welcome back to the Community. I'll be happy to provide the info you need pertaining to the Projects feature in QuickBooks so you can get back to doing what you enjoy. 

It's good to learn you've created estimates and purchase orders using the program. In order to create/manage projects successfully, I encourage you to check out the following article that shows you how to: Create and manage Projects. You're more than welcome to ask other questions as you browse through the article. 

I'll be one message away in case you have other questions. Otherwise, I wish you a great rest of the day.
