Was this a SEP-plan contribution based on earnings from self-employment? If so, you've entered it in the wrong section of TurboTax.
If this was instead a regular personal traditional IRA contribution, your age makes you ineligible to make a traditional IRA contribution for 2016 and beyond. Any personal traditional IRA contribution that you make is therefore an excess contribution subject to penalty every year that the excess remains unresolved. If your modified AGI permits, you can ask the IRA custodian to recharacterize the contribution to be a Roth IRA contribution instead. Otherwise, to avoid penalties you'll want to ask the IRA custodian to make a return of excess contribution before the due date of your tax return.
