I created an IRS account, but the last step requires an activation code which will be sent to me by mail that takes 10-15 business days. So I will wait for the activation code to come to log in and see if I can view the status of my tax return processing. Hopefully it’s just a delay caused by the backlog and not my return being lost or misappropriated. I wonder what happens if by the time they get to processing it the check I wrote is already expired? Doesn’t a check expire after 3 months?
