Please clarify why you believe your return may not be correct.
For Federal income taxes, the tax rate brackets for 2024 are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. To see how the tax brackets apply to you for this year, and for a tool to determine your marginal (the highest part of your income) tax rate, see here.
Note that taxes are often calculated using a different method than the tax tables. For example, if you have capital gains, the tax on those is calculated at the capital gain rate for your income level. If you are self-employed, you may have self-employment taxes in addition to income taxes.
You can preview your return in TurboTax online before filing to find out how your taxes were calculated. See here for details. In TurboTax Desktop, go to Forms mode (click on Forms on the top menu) and review the forms that TurboTax has prepared from your entries.
TurboTax calculations are guaranteed. If your situation meets the terms of the 100% Accurate Calculation Guarantee, Intuit will reimburse the amount actually paid by you to the IRS or state in penalties and/or interest as levied against you in their first notice (i.e., if the notice is not paid, Intuit will not reimburse additional interest and penalties for not paying the first bill timely).
Claims can be filed online here. If you file a 2024 claim and the drop-down menu of years doesn't show 2024 yet, you can choose "2023" and the Accurate Guarantee team will consider your claim.
