Screen time.

How can I get rid of screen time? My brother set my screen time up on my iPhone(8) a while back and I’ve been trying to get rid of it and I guess I changed the password on accident and when I try to put in my email and my password it just tells me it’s incorrect I have no clue if it’s because I’m trying to reset it with a new Apple ID password. He tried to input the same password he used to set up the screen time but it didn’t work I’ve been trying see how I can override it but it just tells me to back my phone up and reset it but won’t that just cause the screen time to come with the data also? (Is there anyway I can go to apple and have them override and delete the screen time) Thank you so much apple community!
