I can’t help bypass or defeat a Screen Time passcode.
If you forgot the passcode, use Apple’s official reset process with your Apple ID.
On iPhone, go to Settings > Screen Time > Change Screen Time Passcode > Forgot Passcode?
Enter the Apple ID and password used to set up Screen Time.
If Family Sharing is enabled, the organizer can change the Screen Time settings.
If you can’t reset it, erase the iPhone and set it up again, then restore from a backup if appropriate.
Contact Apple Support for account recovery or device-specific help.
