You should have reported the Traditional IRA contribution for 2023 on your 2023 return and made it nondeductible. Then TurboTax would have added the 2023 Form 8606 with the basis on line 14 of $6,500 and this has to be entered in the 2024 tax return when TurboTax asks about "Any nondeductible Contributions to your IRA?"
You can amend your return to add the 2023 Form 8606 and mail it to the IRS. Please see How do I amend my federal tax return for a prior year?
Please see How do I enter a backdoor Roth IRA conversion? for additional information.
