I have two amounts in my Box 12 of my W-2 which one is employer and which one is my personal contribution?

[darylbuckles]

Box 12 has DD and W which one is which?

[dmertz]

All amounts contributed to an HSA through your employer, including by payroll deduction, are considered to be employer contributions, reported with code W in box 12.  The employer has already excluded this amount from your taxable wages in box 1 of your W-2, so you do not get to deduction it again on your tax return.

Enter amounts shown in box 12 of your W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.

DD is the total costs of your health plan, both employer and Employee.

W is the total contribution to your HSA, both employee and employer.
