Can competitions go under Activities section in Common App?

I won an international music competition, would it go under activities section in Common App?
i want it to stand out because I performed at carnegie hall because of it but i don’t know if it’s considered an activity because it’s a one-time experience not like, something that I’ve done continuously.
And it wouldn’t make sense to check mark the “I am planning to do a similar activity in college” thing
would the hours just be the amount of hours i practiced for the competition or something?

Definitely put it down, there’s no other place to put it and you absolutely don’t want to leave it out. I also won awards at my music festival (not as spectacular as Carnegie Hall, tho!) I listed the music festival separately from other music competitions I won. Put all the hours of practice down, unless you list them somewhere else under a different music activity, like your school symphony. You don’t want to list the practice hours twice.
