 253, 353! Great honey, keep looking, the IRS cap this year is $18,000. You don't need to go digging through the couch cushions to contribute to the TSP. Those contributions come right out of your paycheck, up to the IRS limit of $18,000 each year. So you can leave those cushions alone. Alright, now go look out in the car. And you don't have to do that either.
