FedEx fees returned

I overnight shipped my H1B documents (then reimbursed by my company) and am noticing now that I have a deposit in my bank account on April 16 from Fedex for the exact amount… My company would not have reimbursed me this way, it would come in the form of a check. Could this be a sign that my application was accepted or denied? Does USCIS typically refund shipping charges of documents if the application has been accepted or is being returned?

The refund is from Fedex. This is a shipment related activity, not USCIS related. Was it delivered on time at the right address?
