No, you cannot e-file another set of W-2s.
If you have already filed, you have to wait to see if your return is rejected or accepted.
If your return is rejected by the IRS, you can add the missing W-2s and correct other errors, then re-file your return.
If your return is accepted, you'll need to amend your return.
To amend your return, please follow the instructions in this TurboTax Help topic.
