Liquid in USB-C charger

Hello. Yesterday, after being hit with the flu, I bought a bottle of NyQuil and mistakingly, I accidentally allowed it to open in my backpack where my laptop charger was and it drenched it. After trying to see if the cord was even salvageable, I tried it on my top right USB-C charging port and it didn’t work. Now, the port isn’t working at all. I have an appointment tomorrow with an Apple Authorized store and I have AppleCare+. I’ve already tried to reset everything I’m just not seeing any advice about the USB-C on the forums. I don’t want to be charged a ridiculous amount and I’m not sure how AppleCare really even works.
