Are you using a VPN? If so, it will "see" you at the point of presence for the VPN.
If you don't know, then that isn't your problem. VPN, or Virtual Private Network is a way to hide your identity and location by routing your connection through the Internet to a location different from where you are, as well as encrypting your connection so it is safe to use with a public Wi-Fi. You would need to subscribe to a VPN service, then use the VPN settings on your phone to connect to it.
So let's put that aside, and deal with your original problem. When you see a different location with 2 FA how far away is it from your actual location? And who is your Internet provider?
Also, does the wrong location pop up at the same time as you are expecting to see an authentication code, or at some random time when you are not expecting a code?
I live in Madera and when I sign in it says that some is trying to sign in from San Francisco. How is that?
I didn’t solve it pressed the wrong but
What is a vpn and how would I get one?
The location is where your provider places the connection to the Internet.
It is all right if you see this location only when you enter your Apple ID (and using 2 factor authentication)
why does my apple id location say that im somewhere else in my location
