FOR 2019
Here's a blank schedule C to see how it works
https://www.irs.gov/pub/irs-pdf/f1040sc.pdf
For 2019 Schedule C Net Profit or Loss goes to 1040 Schedule 1 line 3. Then the total on schedule 1 line 9 goes to 1040 line 7a.
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.
The SE tax is already included in your tax due or reduced your refund. It is on the 1040 Schedule 2 line 4 which goes to 1040 line 15. The SE tax is in addition to your regular income tax on the net profit. You do get to take off the 50% ER portion of the SE tax as an adjustment on 1040 Schedule 1 line 14 which flows to 1040 line 8a. Turbo Tax automatically calculates the SE Tax and Adjustment.
