what do i do when my iphone is disable and i need to use itunes

Turn the phone off and leave it off. Connect it to a computer that has iTunes installed (or to any Mac) while holding the right side button (or the Home button if it is a 1st generation iPhone SE). See the following for complete instructions: If you forgot your iPhone passcode - Apple Support
