It's nice to have you here in the Community, @nicole14.
I'd be happy to walk you through in activating your inactive employees in QuickBooks Online.
Activating an inactive employee can be done in a few clicks.
For more information about changing an employees status in QuickBooks Online, you may refer to this article: Add, edit, or inactivate an employee.
If you need further assistance with this, you may also reach out to our Customer Care Team.
The employee will now be active once again and you're all set.
Let me know if you have any other concerns with QuickBooks. I'll be around to help you out. Take care.
