Hello there, @_mt. Allow me to chime in on this thread.

QuickBooks Online (QBO) doesn't generate W-2s for inactive employees. You'll need to make them active first. You can then generate their W-2s if they have the complete information. However, if the employees have incomplete details, I recommend contacting our payroll support team since they can provide you with the best possible assistance about this matter.

Additionally, you can run a payroll report to get a closer look at your business' finances.

If you require further help with generating a W-2 for your employees, please return to this thread. We'll be here to provide you with the support you need.
