I've seen multiple posts on just about every tax forum I'm on about these S Corp messes.  I believe there is a systemic problem in the S Corp unit and recommend folks contact their Stakeholder Liaison to make them aware of the problems they are having.  The 2553s are not always getting into the system and it seems to be taking YEARS along with multiple back-and-forth contact with the IRS to get this resolved.  If we all scream loud enough in the same direction . . .

I'm in the middle of an IRS webinar right now about the online accounts.  Sounds like you can log in to a Corp business tax account to retrieve the S Corp approval letter (of course, if the 2553 never got processed, nothing's going to be there!)
