Academic Dishonesty Quandry

Short summary: I am a HS Senior. Me and a friend copied off each other for a hw assignment early sophomore year and got caught with plagiarism. My school told me that the incident is not on my transcript and was deleted from any records. Vice principal has told me to check “no” regarding the disciplinary history question (counselor is checking no too) on the common app. Still feeling pretty guilty about it tho. What would happen if I check yes and the counselor checks no?
