If not how could I go about getting that money back?
There is no exemption in Ohio to protect short term disability payments (received from an insurance company, I presume) from being attached. The only way you can get it back would be to file a bankruptcy (presuming you are having financial difficulties (consult a bankruptcy attorney) and getting the money back as a preference payment, presuming a Chapter 7 Trustee abandons it.
A lot of jargon in this response. Consult an attorney if bankruptcy is an option.
