FB/IG unauthorized login but appearing as my device

Hi everyone, I unfortunately responded to a request from a friend on Instagram asking me to copy a link he sent via text. Asked I not click on the link, rather just copy it and send back to him, which I did.  As soon as I did, I realized I was hacked.  Now I show that my device is being used to log in to Facebook and Instagram from a different state than where I live. I have done all the safety procedures, logged out of all accounts, changed my passwords multiple times, etc., but still when I check to see where I’m logged in, it shows “this/my device” logged-in in a city in Washington …i live in California. It’s impossible to contact Meta about this.  How do I remove this user if it appears as my own device is logging in?? Any help is appreciated.
