I paid in about $2500 to an HSA through payroll deduction.
My employer added $479 when I enrolled.
On the W-2 they show the combined amount on W2 Box 12c W
When it flows to TurboTax on Form 8889 is has a zero on line 2 and the full combined amount on Line 9.
No deduction is applied to the 1040 Line 25
