After you file

Mine was not received, accepted, or rejected. It was simply stuck in pending like so many others waiting on TT to correct errors so that it could be refiled. 

If the IRS already has your return then you cannot submit another unless they reject it for some reason. You would have to wait and file an amended return. (If I am understanding your situation correctly) Sounds like you are just waiting on the IRS to finish processing your’s and to issue your refund.
