Where do I update employees after switching to online Quickbooks?

Glad to have you here in the Community, @juliawettrich.

This error means that you can add more information about your employee.

To do that, I'll guide you how:

1. Go to the Payroll menu.

2. Select Employees.

3. Choose the name of the employee whose details you want to change.

4. Make your changes, then Save.

This article also includes more details on how you can edit the employee's information in the future: Add or edit an employee in Online Payroll.

I'm only a post away if you have any additional questions about QuickBooks Online. Take care!
