I put in 10 and my employeer puts in 10. If I don't put the number in, refund is small. If I put the number in, my refund is slightly higher.

Enter amounts shown in box 12 of your W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax. Your employer has already excluded the deductible amount from the amount in box 1 of your W-2 so you don't get to deduct it again. Employer contributions are not to be reported anywhere on your tax return.

You don't enter it anywhere except your W-2. Your box 1 taxable wages are already reduced by the amount you put in the 401k, that's how you get your taxes reduced. You don't also get a separate tax deduction.
