If I resubmitted my return after correcting it. It was rejected due to missing IP PIN number. How long should it take for them to receive and accept it?

[Opus 17]

The IRS does not officially open until January 29.  While they do take some early returns to test their system (and yours must have been one of them) there is no way to know if your return will be picked up early again, or when.  It's up to the IRS and there is no way for anyone else to know when or if your return will be processed early or wait until official opening day.

Your re-filed return went back into pending with the other millions of returns waiting for the IRS to accept/reject returns on January 29.
