Manage Customers and Income

Hi there, and thank you for the screenshot, Caroline2019.

Let me add up some information to locate the missing project.

The project may have been completed, and that's why you aren't seeing it on the project list. You'll want to filter the status to see all of them. Please see the attached screenshot below for your guidance.

On the other hand, choosing Show all events under Events on the Filter page is correct. This will show the history when someone added or deleted the 3307.02.
 

Check out the Use the audit log in QuickBooks Online page to learn more about navigating this feature to keep track of user activities.

Let me know if you need additional information. Just tap my name, and I'll get back to you.

Thank you and stay safe!
