To confirm that your e-filed return has been accepted, check your Electronic Filing Status.
If you provided an e-mail address in the electronic filing steps, you should receive two e-mails (unless you have a spam filter or an e-mail blocking device that would prevent you from receiving them):
Note that the second e-mail will not arrive until your return has been accepted or rejected by the applicable tax authority.
If your return has been rejected, see Most Common E-file Error and Rejection Codes or Correct and Resubmit E-files. It is your responsibility to ensure that your return has been accepted by the IRS or state agency.
Providing your email address may speed up recovery of your information.
