If I had to give you blind advice without looking at your 401(k), put everything in the lowest expense ratio fund.
(1) The lowest expense ratio fund is almost always an S&P 500 index fund. Most of your retirement should be in equities, until you get close to retirement. So that's a decent allocation.
(2) Fees can do a lot of harm, and some plans have choices with 1% or higher expense ratios (aka "annual fee"). Avoiding those is important, and picking the lowest expense ratio is a step in that dierction
(3) Act now. Saving on expenses and being invested beats cash. If you pull out of one fund, and remain indecisive, you can lose out on stock market returns. A bad equity fund still beats holding cash.
