Hello there, @dmcinla-gmail-co.
I'd be glad to walk you through the steps on how to access the reports that will show the termination date of the employee in QuickBooks Online (QBO).
Here's how:
1. Go to the Reports tab.
2. Type Employee Details in the search box, then enter.
3. Click the small drop-down arrow under Employee then pick the employee's name with an asterisk.
4. Hit Run Report.

For future reference about the different types of reports that are available in QBO and how to change the status of the employee, please visit these articles:
• Run payroll reports
• Delete or terminate an employee
