Should I used Code (C, D, W, AA, DD) for HSA contributions?

I am on the step entering my 1099-SA and am being asked to fill in my HSA contributions from Box 12...but there are so many codes I don't know which it is looking for.

@finances TT is asking for your DIRECT contributions.  that would EXCLUDE what is included on your W-2.  

Direct contributions are any additional monies beyond what is deducted from your paycheck. 

p.s. the box 12 HSA code is the "w"

[Karis_F]

Form W-2, Box 12, Code W shows HSA contributions made through your employer's payroll (employer and employee contributions). This amount should carry over automatically from Box 12 of your W-2 to the federal Form 8889 (Health Savings Accounts). 

Form 1099-SA shows your HSA distributions.
