How do I use TurboTax for quarterly payments if I am self-employed?

[ChelseaS · Accepted solution]

To enter estimated taxes that you paid in 2015, follow these instructions: 

1. First, click on the Federal Taxes tab (or the Personal tab in TurboTax Home & Business).
2. Click on Deductions and Credits and make sure to click on Jump to full list or Skip to All Tax Breaks if you don't see all deduction options.
3. Scroll down until you see the Estimates and Other Taxes Paid section and click Show More to expand the section.  
4. Click Start/Revisit next to Estimates.
5. Begin the section titled Federal estimated taxes for 2015 (Form 1040ES).

I don't mean how do I enter estimated tax ALREADY paid. I mean how do I calculate estimated tax I must pay quarterly? There are four payments for self-employed. How do I use TurboTax to calculate and file these payments?
