Calculating Quarterly Tax Payments Using TurboTax?

[messner8000]

I recently filed my 2021 tax return using TurboTax home and business (pc edition).  I started a sole proprietorship in late 2021, and am now looking to file my quarterly tax payment (self-employment tax + income tax) for Q1 of 2022.  I understand I can pay through eftps.gov. However, I need to calculate how much to pay (using form 1040-ES I believe). 

Can my 2021 TurboTax program calculate how much my quarterly payment should be? I could just try to guess it by multiplying my expected income times my combined marginal tax rate and the self-employment tax rate.  But I was hoping to use software that could give me a more precise figure (accounting for QBI deduction, etc.).  Do I have to buy another TurboTax product? Thanks!

Thanks @DoninGA - I followed your advice and was able to calculate my quarterly payments for 2022.  My follow-up question is, I'm operating a sole proprietorship and filing quarterly taxes for the first time.  Using the method you described TurboTax calculated my expected tax liability (that I can divide by 4, and submit for my quarterly payments).  My question is: Is the amount TurboTax estimates I will owe just federal income tax, or does it include the 15.3% federal self-employment tax (i.e., social security and Medicare)? 

Thanks!

@messner8000 That amount of estimated taxes is based on what you entered for all income you estimate to be receiving in 2022.

Sorry, @doninGA  I don't understand.  I understand the tax total is based on all the income I entered.  My question is whether the tax liability is just income tax liability, or if it includes self-employment tax (SS and Medicare) liability.  

To take a way over-simplified example (ignoring deductions, etc., but just to make my question clearer), let's say I enter $100,000 in income, and it will all be taxed at 22% income tax bracket, plus there's the 15.3% self-employment tax.  Would TurboTax say my tax liability is $22,000 (.22 x 100,000) or $37,300 ($22,000 + .153x100,000)?  I assume my quarterly payments need to include self-employment tax, so I want to make sure TurboTax is including that in its tax estimate.  

Thanks!

The answer is yes with a qualification.  During the process of estimating your taxes, you are specifically asked about business income and expenses.  The 15.3% self-employment tax is only applied to the net profit resulting from the business.
