Although technically you have not made your 2024 IRA contribution if you make it later on in 2025, but you are instructed to answer "yes" to get the correct result in TurboTax. That is because you can make the contribution up until the due date of your return in 2025 and have it apply to 2024.
You can make contributions between January 1 and April 15 that are either intended and designated for the current year, or are designated for the previous year. To designate a contribution for the previous year, you must tell the plan in advance that you are doing that, usually with a menu selection on a web site or with a form you send with a paper check if you make deposits by check.
If you plan to make contributions in 2025 that are designated for 2024, report them now. If you plan to make contributions in 2025 that are intended for 2025, don't report that now.
