[US] Received hundreds randomly on CashApp

I received a few hundred dollars on Cash App and the sender is requesting the money back. I do not want this money, but I do not know if they’re genuine or trying to scam me in some way.

So they sent money apparently for a piece of furniture. Then they asked for a refund about 5 times now. I asked them through CashApp how they could have sent it to me of all people. They said my name is similar to who they were trying to send it to. But here’s the thing: the “intended recipient’s” profile name is, for example, Rebecca Barnes, but the cash tag is, for example, $janaebarnes while my cash tag is, for example, $janaebranes (one letter switched). I just find it hard to believe that someone with the profile name “Rebecca”would have a cash tag under “Janae.” I know people have different profile names and $names, but this seems sketchy.

Well, it all seems too convenient. I don’t want the money and I’m not planning on spending it, but I don’t want to return it and then I’m somehow out hundreds just for being a good person.
