Estimated tax payments are to cover all taxes on the federal return based on your estimated income ... it will cover the federal & SE taxes ( FICA is on a W-2).
Self Employment tax (Scheduled SE) is generated if a person has $400 or more of net profit from self-employment on Schedule C. You pay 15.3% for 2014 SE tax on 92.35% of your Net Profit greater than $400. The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire. You do get to take off the 50% ER portion of the SE tax as an adjustment on line 27 of the 1040. The SE tax is already included in your tax due or reduced your refund. It is on the 1040 line 57. The SE tax is in addition to your regular income tax on the net profit.
For SE self employment tax - if you have a net profit (after expenses) of $400 or more you will pay 15.3% for 2015 SE Tax on 92.35% of your net profit in addition to your regular income tax on it. So if you have other income like W2 income your extra business income might put you into a higher tax bracket.
You must make quarterly estimated tax payments for the current tax year (or next year) if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits.
- 2. You expect your withholding and credits to be less than the smaller of:
90% of the tax to be shown on your current year’s tax return, or
100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months.)

Let me ask my question another way. Self-employment requires you to pay taxes normally paid by the employer as well as taxes I would normally pay. Are both normally reflected in the calculations in the 1040ES or does the 1040ES only reflect the part normally paid by the employer?
How does TurboTax calculate my estimated tax payments?

Instead, it appears TurboTax calculated that my 1040 ES should have been $426, so it ADDED $426 to $450 to get a total tax due (for this portion only) of $876. Then it subtracted $426 that I paid, so that it showed I owed an additional $450. Did TurboTax make a mistake?
