I had an email on file where I supposedly being sent rejection notices but since I no longer had access to that email, I never got notified. Can they resend the email?

Interesting ... to efile you had to enter the code sent to that email so in the 24 - 48 hours after filing when the email would have been sent that email account was no longer active ?  

So that this doesn't happen again update your email address now :

And now for the 2018 return ... it cannot be efiled any longer ... it must be printed, ink signed and mailed.  The rejection reason is immaterial now.
