After you file

OK ... the original return was processed and the original refund was released ... good step 1 done.   Now the IRS has to recalculate the change that you did NOT have to amend the return for and they are not yet done doing those and there is no way to track it's progress which is why you are not getting an answer.   The fact that the amended return was even considered before the IRS correction would be out of character for them this year ... again it is possible that the amended return in the system slowed up the process so all you can do now is wait.
