I have a 1099-MISC for writing entries in a textbook (I am a university professor). It seem related to my job, but I am not self employed.

The box completed on the the Form 1099-MISC will determine if you were considered self-employed. 

If Box 7 has an amount in it, then you are considered an independent contractor. You will need to prepare a Form 1040 Schedule C or C-EZ and deduct any business related expenses, no matter how minimal, against your income. You may also be subject to self-employment tax if your net Schedule C income is $400 or more.

To open the Schedule C in a TurboTax CD/Download version do the following

1. Type Schedule C in Find
2. Click the Jump to link
3. Navigate through the program to begin entering your income and expenses

You income will appear on line 12 of the Form 1040 Schedule 1.

If Box 3 of the Form 1099-MISC has an amount, then you will report the amount has Other Income, and you will not be subject to the self-employment tax.

To enter the information in TurboTax due the following:

1. Select the Personal Income (or Wages and Income) tab.
2. Click the I'll chose what I work on button
3. Scroll down to Other Common Income
