I paid the alternative minimum tax quarterly during the 2016 tax year. Where do I enter this tax information?

Where do I enter my estimated tax payments?

Enter any federal, state or local estimated tax payments you’ve made under Estimates, in the Estimates and Other Taxes Paid section. You'll find this section in Deductions & Credits under either the Federal Taxes tab or the Personal tab, depending on the product. For a shortcut, type “estimates paid” in the search box and use the “Jump to” link.

Your state and local tax payments are automatically transferred to your state return. We’ll also use them to determine whether you’d benefit from itemized deductions, instead of a standard deduction.
