How to enter income from Self Employment
To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax. Self Employment tax (Scheduled SE) is automatically generated if a person has $400 or more of net profit from self-employment. You pay 15.3% 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.

You were treated as a contractor for your side job, not as an employee. When you're paid this way, no taxes are withheld from your earnings and they are reported on a 1099-MISC (instead of a W-2). As a result, the IRS treats you as self-employed, and you'll need to pay both income tax and self-employment tax (Social Security and Medicare taxes).
