Let me share some details of W3 form, burbz.

The W-3 form available in QuickBooks Online is only for employer's copy not the official form for submission. When we file your W-3 electronically, we provide the necessary information that is acceptable to the agency. Running Payroll Tax and Wage Summary has the details for W-3 as well.
 

Here's how you can run a report for Payroll and Wage Summary:

1. Click the Reports menu, then choose Standard, then select Payroll.
2. In the Payroll section, select Payroll Tax and Wage Summary.
3. Choose the Date Range from the drop-down.
4. Enter other customization base on your preference.
5. Hit Run Report.

I can see that this article can be handy: Run a Payroll Tax and Wage Summary report.
