Loan holder wants a check from the insurance company that I already cashed and used to repair my car
There are at least three financial institutions involved here: your insurance company's bank, the money center, and your bank. Normally, they would keep records, but given that the money center didn't even ask for your signature, "normal" probably doesn't apply to them. Still, you can still ask them what records they have, in addition to the other two institutions; the company's bank and your bank likely have copies of the check.
