Where did you read that? If you are filling out your return by hand manually yes you need to enter it. But Turbo Tax is a program that does the entries for you and fills out the forms. Especially that one. You just enter your income and expenses and Turbo Tax fills out Schedule C and calculates the net profit or loss. Turbo Tax calculates the self employment tax on your Net Profit and fills out the 1/2 deduction. That's why you use Turbo Tax.
