She’s sending an unknown package

Just got a notification from USPS informed delivery that I have a package coming from the city where my exwBPD lives. She’s the only one there, besides my divorce lawyer, with my mailing address.

I know it’s not from my attorney because the zip code is the suburb where my ex-wife lives, and my attorney’s office is 45 minutes away from said zip code. Plus, I would know if my attorney is sending something to me. I have really bad anxiety about what she could be sending. We’ve been NC since October 5. I plan to return to sender, but the anxiety is so high.
