Does anyone know how to complete a w-4 form an employee who doesn't have a SSN?

I appreciate your time reaching out to us here, usermepitesky.

To complete the employee setup, you can temporarily enter a dummy SSN on the W-4 page. Once you have the correct SSN, please make sure to update the information by following these steps:

Note: It's important to update the SSN before submitting the W-2 form. This is to match the employee's name and SSN with Social Security records. 

1. On the left panel, go to Payroll > Employees.
2. Click on the employee's name, and select the pencil icon next to Pay.
3. Under What are employee's name withholdings? section, click the pencil icon next to the status.
4. In the W-4 page, remove the dummy SSN and enter the correct information.
5. Hit Done.

Please see these sample screenshot for a visual guide:
