I think perhaps you are confusing a 401(k) with an IRA. Also, Roth plans are post-tax, so there is no deduction for them.
If you contributed to a Roth 401(k) or a traditional 401(k) through your workplace, you should not enter that information in the IRA section. The contributions would have already been properly accounted for in your W-2.
