[US] Got a random $829 refund from Amazon?

Hi everyone. I just checked my credit card and saw that it was debited $829.90 yesterday from Amazon. I haven’t bought or returned anything from Amazon in a long time. On the charge jt has the address “410 Terry Ave N, Seattle WA.” I looked up the address and it looks like an Amazon site.

So I’m wondering now is this a scam? A mistake? What should I do? Call my bank? Call Amazon? Keep it? lol I’m just a little shocked and confused about this.
