Failed Passcode Attempt on the Screen Time

I have now had 11 failed attempts when trying to change the screen time settings and apps allowed. How can I recover this? I have tried every code. It is a Iphone 7+ and under Screen time- Content and Privacy Restrictions. When I click on either Allowed Apps or Content Restrictions, you must enter a 4 digit passcode. I do not know the passcode, and again, I have 11 Failed Passcode Attempts. ANYONE???

Thanks!!
