Symphony Health Solutions Check Scam Received a check for $1980, no other additional information. San Mateo California

I receiced a check in the mail and it didn't include nothing else. The information from the check is the following

Symphony Health Solutions

PO Box 210620

Cincinnati, OH 45221

(Note: I googled the address an it's belongs to the University of Cincinnati)

Citibank, N.A.

Citibank Delaware

One Penn's Way, New Castle DE 19720

Amount: $1,980

Routing number: 031100209 (note: this does match to the correct bank)

Account number: 38642025

My husband spoke to his lawyer and he was at a loss, he said he knew there were red flags and that this looked like a SCAM, he just couldn't figure out what angle they were working, since there were no instruction to send any money back, like other scams ask you to.

I called the company and someone took down my call back number and other information from the check, I have not heard back (3rd day)

I still don't know what is going on, and how they got my name and address. It wasn't until today when I googled again that I found a report on this site. If you google the RN and AN from the bank info you will also find another post regarding a questionable check (they do not mention Symphony in their post)

If anyone has any idea of where should this be reported, or what exactly is going on, I would appreciate any and all information.

Thank you.
