15 and need a bank account

Hi everyone, I'm a teen (15 years old) living in the U.S. After working for some time I have ~2,000 in cash that I'm hoping to deposit in a bank.

My mom says I have to move out when I turn 18 and support myself on my own. She'll help pay for my college tuition but nothing else.

I have a two questions:

1. What kind of bank account should I open? And how should I ask for it when I'm in the bank?

2. There's a high chance my mom will try to take some money for herself. Is there any way I can prevent that or at least notify me when that happens?

Thanks y'all!!
