Get your taxes done using TurboTax

Since it's from your employer, it really should be on your W2 with the correct withholding taken out for social security and medicare tax.  I would start by requesting a corrected W2.  If you get no where with that request, I would enter it as Other Reportable Income under the Miscellaneous Income section.

Follow these steps: 

1. Sign in to TurboTax Online, click Continue your return, then pick up where I left off (if you are using TurboTax CD/ Download, then just open your return on your computer);
2. Click on Federal Taxes at the top of the screen;
3. Go to Wages and Income;
4. Toward the bottom, you will see a box to click that says Add More Income.  
5. Scroll down the page to the last section titled: Less Common Income and click show more;
6. Select start or update next to the last topic titled Miscellaneous Income, 1099-A, 1099-C;
7. Scroll down to the last option titled Other reportable income and select Start or Edit;
8. Click Start next to Other income not already reported on a Form W2 or Form 1099;
9. Click YES to Did you receive any other wages;
10. Continue past Wages earned as a Household Employee, Sick or Disability Pay, and select YES again to the question Did you earn any other wages?
11. Select Employee Compensation that was not reported on a W2;
12. Continue answering all questions.  The Reason Code you should use is H;
13. Then click Done.
