You can try a couple of things. If the IRS correctly processed your injured spouse form but turned over the funds to ODJFS anyway, you can attempt to get them to require ODJFS to return the funds. I don't do tax so you would be better talking to a tax attorney on how and whether that's possible. The other front is to file a complaint against ODJFS if you are given an option to request a state hearing on the notices you get from them. Barring that you can file a complaint in the Ohio Court of Claims against ODJFS but they may attempt to claim that the money was after all turned over to them by the IRS and they have no choice but to process it. So you will still need to make sure that the IRS processed your injured spouse form and/or notified ODJFS that the payment was made in error and they should send it back. In general you should never, ever, ever assume with a bureaucrat that they will document your conversation. Keep a notebook of who you talked to and when and what was said, and follow up with a letter, fax or email to them that confirms what was said. Hope that helps and come back and tell us how it worked out.

You probably should contact the IRS Taxpayer Advocate Office and see if it can help you obtain the refund to which you are entitled. The facts that you have outlined are somewhat confusing but it appears that 90% of the tax refund (your portion) was applied to your husband's child support arrearages owed to you, which appears to be improper because you have obtained injured spouse relief. Here is a link to the IRS Taxpayer Advocate Office in Ohio. http://www.irs.gov/uac/Contact-a-Local-Taxpayer-Advocate-(LTA)-in-Ohio.
Good luck in resolving your tax problem!
