Since your return has been accepted, you will need to amend your return to include the
Form W-2. You cannot e-file an amended return as this cannot be filed
electronically. The form is only filed on paper, so it will need to be
printed and filed by mail.
Please see the following TurboTax FAQ for instructions on how to amend your 2016 tax
return in TurboTax.
