If you have a name, go to the post office and tell them your story. They may help you, especially if the name is also a PO Box user, as it is a violation of postal law to open misdelivered mail, let alone cash a check fraudulently.

They may also be inclined to help you to help dodge responsibility for misdirected mail.

The name is not really legible, at least not to me: Here is the back of the check in question: https://i.imgur.com/ICBydCo.png

Nevertheless I will try to talk to someone at the post office about it. I had covid all last week, so didn't want to do it then.
