I have physical copy. Did IRS actually acknowledge the unsigned e version?

You can verify that you submitted an efile and whether the IRS accepted or rejected it using this link:

Do you think you need to mail it in?

When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. What does it say?
