Here's the clumsier navigation method, but the steps above are usually easier.
Federal Taxes tab
Deductions & Credits
If a page says "Your Tax Breaks", do not choose "Other Income Taxes".
Instead, keep scrolling further down the page to a list of "All Tax Breaks" (you may have to click a tiny blue link that says "Show all tax breaks".)
Then keep scrolling down to "Estimates and Other Taxes Paid"
Expand that category ("Show more") and the first topic is "Estimates."
