Information from Form 1099-MISC can be entered in 2 different locations, depending on your situation:
Self-Employment - when the income relates to your normal job or something you do regularly. This income will end up on a Schedule C, is subject to self-employment tax, and expenses can be entered to reduce the taxable amount.
Other Common Income - something you did only once, not related to your normal job, and don't plan on doing this type of work in the future.
If the second example sounds like you, enter this information in TurboTax 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."
