401k

I recently got fired from Aldi so I won’t be posting in this thread anymore but I did need advice on one more thing. Aldi was my first job that I had a 401k with. What happens to that money? I’m a very young adult and I have nobody to teach me on this. Do I get it? Like what happens to it ? And how can I contact Aldi to give it to me? I’ve already have had my access taken away to myHR etc… thanks for your help guys!
