Need advice on my 401k and Roth 401k

I started my job last April, in my mid 20s and looking to be aggressive in my investments. I’m contributing 11% to 401k, 8% to Roth 401k, and my company offers 4% to every paycheck. No Roth IRA. So far I have vested $10.5k in 8 months.

My account shows I’m investing in Black rock index 2060. I know little about retirement and not sure if I’m doing it right.

Should I be investing in something else other than Blackrock 2060k? I haven’t done anything in my Schwab account besides increasing my contribution rates.

Do you guys think I should change my contributions? Perhaps opening up a Roth IRA or put more into Roth 401k? Next month I have a meeting with an advisor at Schwab to discuss this but I want everyone’s opinion.

Thanks
