To prepare estimates for next year you start with your current return, (if you can't get back into your return try this, On the Tax Timeline page you have to select Add A State to get back into your return). But be careful not to change anything on your real return.
You can just type W4 in the search box at the top of your return , click on Find. Then Click on Jump To and it will take you to the estimated tax payments section. Say no to changing your W-4 and the next screen will start the estimated taxes section.
