If you have a 1099-MISC with income paid to you reported in box 7, then as far as the IRS is concerned, you do own a business. You are considered to have been self employed and "in business" for yourself when you earned that money. Therefore, all of your business income & expenses is required to be reported on SCH C as a part of your personal 1040 tax return.
Our SuperUser is correct.
Allow me to add this:
Your question is very common - sorry for the confusion.
Information from Form 1099-MISC can be entered in 2 different locations, depending on your situation:
If the second example sounds like you - enter this information in Turbo Tax as follows: Go to Federal Taxes - then click on Wages & Income, next look for the section: Other Common Income, then click on Start to the right of "Form 1099-MISC."
I hope this helped you. Thank you for using Turbo Tax.
Be careful of your selections if the income is reported in box 7 of the 1099-MISC. The exceptions for that income to not be SE income are rare. The most common rarity for box 7 income, is if it's scholarship money, grant money, or money for participating in a "study group" (usually in the medical field)
