I HAVE CODE DD IN BOX 12A DO I PUT THIS IN CONTRIBUTIONS PERSONALLY MADE NOT THROUGH EMPLOYER?

[AnnetteB6 · Accepted solution]

No, the only place that you need to put that information is in box 12 of your W-2 with code DD.  

This represents the total cost of what you and your employer paid for your employer-sponsored health coverage.  It is not reported anywhere else on your tax return and does not affect any calculations on your return.  It is informational only.

If you are asking about contributions made to your Health Savings Account (HSA), those are reported in box 12 with code W.  That amount is automatically transferred to the correct tax form for your HSA.  You would only enter any additional contributions that you made to the HSA directly, not through employer payroll deductions, as you go through that section of your return.
