My 401K through my job is a roth ira account. Do I list my contributions to my 401K in the "traditional IRA and Roth IRA" section of my return?

Check again with your employer. 

If you have any type of Roth as a retirement account it will probably be a Roth 401(k) or 403(b) plan.

Look at your W-2 in box 12 is an amount listed with a code of AA?  If so you are contributing to a Roth 401(k)

Or is the code a BB?  If so you are contributing to a Roth 403(b)

The amounts shown in box 12 are not entered anywhere else on your tax return.

As DoninGA implies, a 401(k) is not an IRA.  Enter amounts shown in box 12 of your W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.
