Box 12 with code W is added to my total income after I uploaded W2. Code W is HSA contribution amount. Why is this added to my total income?

I clicked "Explain my taxes and what I see in my total income is W-2 wages:$xx (from box1) and 
1099-SA HSA and MSA distributions:$xx (from box 12). . Also this box 12 HSA amount is less than 2023 maximum but Turbotax says I over contributed and need to withdraw all of them. Can anyone please explain? Thanks
