Q: FORGOT THE ENCRYPT IPHONE BACK UP PASSWORD
See "Encrypted Backups" here:
Create and delete iPhone, iPad, and iPod touch backups in iTunes - Apple Support
In particular:
"If you can't remember the password and want to start again, you must perform a full software restore and choose set up as a new device when iTunes prompts you to select the backup from which to restore."
