I agree that the TSP F Fund will do badly as rates rise.
I can’t give individual advice, but would point out that the L2030 Fund is only 6% F Fund, so you have very little exposure to bonds in your portfolio as currently constituted.
The L2030 has a lot more G Fund (29%) than I would want to have except in a last resort safe haven, but otherwise is not bad. (Note that people talk about the G Fund as if it was a bond fund, but it is not. With a real bond fund, your principal can decline, but with the TSP G Fund, your principal is completely safe.)
