Where do I input payment of state estimated taxes for 2020 on the turbotax state review?

Please see the screen shot below for the entry point:

You can type estimates paid in the search box at the top of your return and click Find and it will give you a link to Jump To it.

OR

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 (Home & Business)

Deductions and Credits at top

Then scroll way down to Estimates and Other Taxes Paid

Estimated Taxes - click the Start or Update button

You enter state estimated payments under the federal side (because they can be a federal itemized Deduction).  THEN after you finish filling out the estimates under Federal you need to click on the State Tab at the top and start the state return over for it to update.

You have to pick the right state from the drop down box and enter the right payment dates.
