Can't find where to enter estimated tax paid. Deductions and Credits section doesn't have that sub category in my online form.

To enter, edit or delete estimated taxes paid (Federal, State, Local) -

Click on Federal Taxes (Personal using Home and Business)
Click on Deductions and Credits
Click on I'll choose what I work on (if shown)
Scroll down to Estimates and Other Taxes Paid
On Estimates, click on the start or update button

Federal estimated taxes paid are entered on Form 1040 Line 26

To enter Federal or State Estimated Taxes Paid, including a state estimated payment made in January for the prior year, go to

Federal on left or at top (Personal for Home & Business)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Estimates - click the Start or Update button
