I provided the shortcut method above to go directly to the estimated taxes entry section. If you want to use regular navigation, here's how. So between the 2 methods, you should be able to use one or both of them.
When you click in the left column tab for Deductions & Credits, it may take you to a page called "Your Tax Breaks". That shows the "Tax Breaks", i.e., deductions, that someone has already worked on this year or that TurboTax is expecting from what was entered last year. Lower on that same screen should be a button or link for "Add more tax breaks" or "Show more tax breaks" or similar wording. When clicked, then the screen should expand, and all the deduction topics are displayed including "Estimates and Other Taxes Paid." Then that topic can be expanded further to get the subtopic Estimated Tax Payments.
