Trying to bring vape through TSA(traveling with parents)

I’m traveling from Washington DC to Utah and I bought a vape here under age and want to take it home, but I’m not sure if they will search through my carry-on bag because it will be unidentifiable. I just need to know from other people that haven’t done it will they check my bag if I have a vape in it??? I’m also traveling with parents. That’s the only reason if I was by myself it wouldn’t matter.
