The message "W-2s are sent" indicates that the W-2 forms have been transmitted to the relevant parties, such as employees or the IRS. However, this does not necessarily mean the e-filing process has been initiated. I'll be providing details below, CMC.
Since you haven't initiated the e-filing process and haven't received any confirmation emails, it is evident that the forms were not submitted twice. Once the forms are sent, it would be helpful for the employee to access and verify their receipt through QuickBooks Workforce. If you haven't invited them yet, check out this article for guidelines: Invite your employees to QuickBooks Workforce to see pay stubs and W-2s if you use QBDT Payroll.
Moreover, you can explore this article to learn how to check the status of the payroll tax forms and payments you sent electronically through QuickBooks: Check the status of your payroll tax payments or filings sent through QuickBooks Payroll.
Furthermore, if you need to obtain a copy of your W-2s in QuickBooks, refer to the section on printing W-2 forms in the QBDT section of this article for comprehensive details: Print W-2 and W-3 forms.
