Hello there, missjulia. Allow me to share some information regarding the EFW2 format. 

EFW2 stands for electronic W2. The deadline for electronic filing in QuickBooks is January 30. Since you exceeded the deadline for e-filing of W2-s, in the meantime, you can download the PDF and manually file it with the SSA. 

Meanwhile, you can run a report to view the payroll wages, taxes, deductions, and contributions in QuickBooks Desktop for future use. 

Whenever you need assistance with your W-2s, you can return to this thread anytime. You can use the reply button below to enter your queries.
