Who said your refund can't be electronically? Did your tax return efile reject?
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. And check your spam folder for them.
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?
If it says Ready to Mail that means YOU have to print out your return and mail it to the IRS and state yourself.
