Employer HSA,1099-SA and TurboTax

[DtaxPayer]

So I have a Standard Employer High Deductible Health Plan accompanied by an HSA account.  In 2023, I contributed the maximum allowed and I am over 55 and my employer contributed the last $1000.  So no excess contributions.  And of course this is all pretax money.  My employer gave me a 1099-sa as expected.  I spent over $6000 of this HSA on medical expenses in 2023. 

So here is the part I do not understand.  After I input all the information into the TurboTax software from the 1099-s along with my 2023 HSA spending, it gives me this big credit on my taxes.  That is a bit concerning to me because this HSA money is already pre-taxed.  Am I missing something here or is this the intended way the government set this up?  I have found no information backing up what I am seeing in TurboTax.

What exactly is "this big credit"? What credit does it give you? On what Form or Schedule, and what line?
