Don’t Know Screen Time

I’m getting more and more frustrated with not knowing my screen time passcode. I share an Apple ID with my family and no one remembers setting or changing a screen time passcode or setting a restrictions passcode. I just went through the hassle of resetting and erasing my entire device to try to get the password. And yet, I still won’t let me in. Before resetting it, I had gotten to the point where I would have to wait 60 minutes between every wrong attempt. So even after resetting and erasing it, it still is a passcode that I do not know. Help??
