HSA 1099-SA input in turbo tax gets my federal tax due increased

Hi,

 

I have HSA 1099-SA form with 5700 gross distribution in 2021 tax year, shown in form box 1, and box 2  has 0.00 in there.

 

when I typed this 5700 into turbo tax, my federal tax due jumped up by 2000 dollars, I thought HSA money distribution from my health expense claim will be tax free, isn't that true? Thanks!
