Hi bimmy,
You can update your employee's social security number to make the correction.
- Select Workers from the left menu > Employees.
- Select the employee's name.
- Select Edit employee.
- In section 1, select the edit (pencil) icon to update W-4 information.
- Delete the displayed digits.
-
Retype the entire number.
Then, amend these forms using the correct SSN if you've filed the forms. Here's an article for more additional information: Correct An Employee's Social Security Number.
You'll also want to print W-2 forms for your employees: For future reference, please check this article: How to Print W-2s Forms.
