Here are the fund options. The first number is the expense ratio and the second number is the 1 year return for 2018. I only included one of the target date funds. Also if you look in that fund's fact sheet, it says gross expense ratio 0.06%, so I'm not sure which one is correct.
Target Retirement 2055 Fund 0.04 -7.97

The target date funds are not made up of any of the other index funds or active funds. Even though their expense ratios are very low, they contain a lot of international, real estate, commodities, TIPS and bonds, which I don't like.
I put the index funds that four of the active funds are directly comparable to. For large scale mutual funds, I don't believe active management can consistently beat the index after fees, so I recommend just using the index funds.
So if you want to mimic a target date fund without real estate and commodities, you can use:
- S&P 500 Index Fund and Russell Small Cap Completeness Index Fund in a 4:1 ratio which covers the US total stock market.
- International Stock Index Fund in whatever ratio you choose to the sum of the above 2 US funds. Vanguard does 60% US : 40% Intl. I do 80:20.
- You can start shifting to bonds as you get older.
And yes, there is a $7.33 per quarter fee or $29.32/yr, but as your balance grows the percentage gets lower and lower. e.g. at $100k it's 0.03%.
