My parents kept my college fund in an investment acc and gave it to me recently, I’m going back to school and need the money. How do I get it out??

I’m very very new to investments and brokerage accounts, how do I transfer the money out of the account? Do I have to call my advisor and sell everything off to get the balance transferred? It’s currently saying that I only have $0.57 to transfer. My parents just said “here” basically and didn’t teach me anything on how to handle the account. Any knowledge helps. Thank you
