I appreciate your tireless support using QuickBooks Products, Liz. Firstly, you need to click the import option in QB Time to sync the employees that are set as No longer on payroll in QuickBooks Online Payroll. I'll provide you with the steps.
Here's how:
- Go to Time, then click Go to classic QuickBooks Time.
- Click on My Team.
- Select QuickBooks Payroll beside of Help icon.
- Click Import, then wait to click View Log.

5. Go back to, My Team.
6. Select the employees that are no longer on payroll, then click Edit to check their information.

7. You'll now see that they're no longer salaried even if we can't click the Archive option.

You can refer to this article to set your employees as active again: Edit or change employee info in payroll.
When this is all resolved, you can now approve, unapproved, and reject timesheets for QuickBooks Time to all active employees.
