HSA W2 box 12w

I seem to have a dilemma. On my w2, for 12w, my employer HSA contribution lists 6,900. However, only 1,000 of that is actually from my employer, the other 5,900 was contributed by me. If I leave the number, I can't edit it when Turbo Tax asks further questions regarding the HSA. If I put in 1,000, and accurately break it down in the later HSA questions, Turbo Tax tells me I over funded the account by 6,900, which doesn't make sense. So, I'm a little lost.
