Should I say I got a misdemeanor

I got a misdemeanor for underage drinking and it will eventually be sealed but I am in an alcohol diversion program at the moment. I want to transfer colleges and the application process questions wether I got a misdemeanor or not, should I admit to this misdemeanor or say no or leave it blank. What are the chances that I make it into this average college if I admit to this misdemeanor

Can you wait until after it’s sealed to submit the application?
