So the IRS system has no way of catching a double payment.
Their system is over 20 years old and had no protocol to catch it so it goes into cyber space. There won't be general record of it.
I had to file with the IRS, and it's a trick on it's own to navigate the switchboard to get the right person to even file it.
But eventually she was able to check it and realize to payments were made (the second one wasn't registered to my account because once it's paid your account closes) she was able to process a return and even gave me back most of my "late fees I was charged because their system glitched".
Note. It still took 3 months after that for the money to come back. Best of luck to you. Just keep fighting and have your bank record to prove the money was taken by them twice. They can trace it on their end. They won't want to. But the right person can and will.
