Did you just log in to your Apple ID, and are concerned the location is different? If so, that login triggered this.
If you did not just log into your Apple ID, change your password immediately.
Login notifications are “correct” if they’re geolocated within the same country, and if the browser reported is in the same general browser family.
Enable two-factor authentication on your Apple ID, unique and robust passwords across your Apple ID and all password-reset paths, ensure your cellular carrier PIN is not known, review and remediate the list of security recommendations shown by Apple in Settings > Passwords, and update to your iPhone, your Wi-Fi router firmware (if any), your printer firmware (if any), and other gear to current.
Password re-use is deadly to security, just as soon as one use of the password gets exposed somewhere all of the other uses are at risk, and breaches are fairly common.
