Here's an alternate way to get there, but it's clumsier:
Federal Taxes tab
Deductions & Credits
If a page says "Your Tax Breaks", 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."
