This result implies that you've entered a Roth IRA contribution in excess of the amount that you are permitted to contribute and TurboTax is calculating an excess contribution penalty. Either you have insufficient compensation to support the contribution, your modified AGI for the purpose and your filing status makes you ineligible to make some or all of the contribution, or you've entered more than the overall annual maximum IRA contribution for your age. Make sure that you are not entering Roth 401(k) contributions as a Roth IRA contribution.
