Local backend

I created a website at local but I accidentally wrote my real web page URL on settings ( https://prnt.sc/sdz0pz ) and saved it. Now when I try to login on Local backend ( https://prnt.sc/sdz11y ) I will be redirected to my real web site ( https://prnt.sc/sdz1cb ) on which is life.
How can I change it so that I get into the Local backend instead?
