Roth IRA beginnings?

Hi, Im looking for some advice on where to open a Roth IRA or how to get started. I'll give some insight on my finances and investments as well. I currently have a 401(k) with my employer who does a match of up to 3% of my contributions. I'm wanting to acquire knowledge and learn all this before I decide to leave the company of course in a few years. Im not super big on finance and thats why I'm here.

I have an annual salary of 65k, currently have 12k in my 401k, 3k in a WF savings account, about 4k in investments, and an auto-loan of 20k. My rent expense is about 1k due to me moving out of my parents house 2 years ago due to them being drug addicts, phone plan $100/month, and spotify $14/month.

Any advice would be appreciated.
