No, you will not be charged to determine if you are eligible for the IRA tax break.
If you purchase and enter an IRA on your return, you may be required to upgrade to TurboTax Deluxe which is not free.
However, you may be able to increase your refund (or decrease taxes owed) by purchasing a Traditional IRA, and you have until April 18, 2017 to do so.
Although the Roth IRA is not tax deductible as is the Traditional IRA, both may qualify you for the Saver's Credit, which may also increase your refund.
