Insurance fraud

Long story short, we got backed into. We called our insurance that same day. We eventually went through theor insurance. We got the check for $1500. 2 weeks later we got a check from our insurance for $1000. This is called double dipping, I realize that. We haven't spent the money nor are we going to. She deposited it Friday. My question is if I call our insurance company Tuesday and send them the money all is good correct? No harm no foul or are we in trouble since it was deposited?
