19 and a beginner- where to open my Roth? What should I be looking for? I’m 19 years old and looking to open my first retirement savings account, and I’m not sure where to open it. I’m considering Fidelity and Schwab because I have stock with both companies, but I’ve heard Vanguard has very low fees. 
To be honest, I’m not even sure what I should be looking for to compare the three- what should I be prioritizing? How much control do I get over the investment of funds in my account? Will I be communicating frequently with a broker (so customer service is a priority) or is this more of a ‘send a check every month but otherwise forget about it’ type of deal (in which case low fees would be more important)? 
I hope this is clear and thanks so much for any advice- sorry if my questions are too basic for this sub!
