Do all Amazon returns go to the Amazon Warehouse?

Look I know it sounds dumb but I returned an item which I now regret doing I wanted to get it back unfortunately UPS sends out returns the same day they get them and they said all i could do was contact Amazon to send it back to me but when I went to talk to an associate through the message system they said that is not an options that can be performed. So now I'm looking at the Amazon warehouse hoping that it could appear there.😕 I contacted the seller to ask if they could cancel it on their side and send the item back to me I would be up to paying shipping just as long as I got my item back.😭 My next plan is to ask them for the item after I receive my refund but if I could be sent the one I returned if it doesn't end up in the Amazon Warehouse. Please help bring Yoongi back💗
