1) how long ago did you file Alabama? IF it was many weeks or months ago, then I would suspect that someone else did file an SC tax return recently...but then mis-typed their email address....and that mis-type just happened to be yours.

2) You did file recently with no other acceptance notice before?
....2a) A state mis-type in the email notification? Print out yoru tax file to a PDF, and look at the actual forms to make sure SC isn't in there.
....2b) Call TTX on Tuesday (Monday is a holiday) and let Customer Support know there's an issue:
