where do I calculate my 2025 estimated state taxes?

[DawnC]

You will get the option at the end of your state tax preparation.   You can enter your expected income and deductions in TurboTax or Tax Caster to get a feel for 2025's taxes.   

In TurboTax, you can go through the estimated taxes for next year section.   If you already filed your return, you will need to click on Add A State at the bottom of the home page to access your return.    You can do this for your federal taxes and your state taxes, if applicable.
