I recognize the relevance of efficiently handling your payroll forms in QuickBooks Online (QBO). I can guide you to fix your employee's W2 and get back on track, Mahur.
Correcting any W-2 mistake depends on how your taxes and forms are managed. Bear in mind that some data on the W-2 form can't be fixed within the program. This includes the following:
Employee prefixes (Mr., Mrs., etc.)
Employee address
Business Name
Business address
If your automatic taxes and forms option is activated, you'll have to get in touch with our Payroll Support Team to request a correction, as they're the ones who can update the data and submit a W-2C on your behalf.
If your automatic taxes and forms feature is disabled and hasn't submitted your W-2s yet, you'll need to fix the issue in your product and then file your W-2 forms as you usually would.
