Is this still the case in 2021? I tried to file my returns electronically and had an error that could not be corrected, so I also had to file by mail. I also did not want to send a duplicate payment. When I went to "Open Return" I got the message screen that said "Hello there--looks like you've paid (thank you!) but haven't e-filed yet. If you leave now, don't forget to come back and e-file later. That is, before the filing deadline."
Since this indicated that I'd paid electronically, I didn't send a check to the IRS or state revenue office.
How can I check this?
