I'm here to help you amend your employee's ID, @MikeyBrook.

You'll have to update your employee details so the ID will match. To update your employee's information, follow the steps below:

1. Go to Payroll and select Employees.
2. Select the name of the employee whose details you want to change.
3. Make your changes, then click Save.

For more details, see this article: Add, update an employee record in QuickBooks Online.

 Also, you can contact our Customer Support Team for further assistance. They can help you update your employee's ID. Just click this link on how to reach them: QuickBooks Online Support.
