You'll report it as cash income, since that's basically what it is. Understand that as far as the IRS is concerned, you earned that income while self-employed and "in business" for yourself. So that income and any expenses associated with that income will be reported on SCH C as a part of your personal 1040 tax return.

 You will need to use TurboTax Self-Employed in order to enter your income and expenses.  

 

Dont' let the above potentially confuse you @collazo63  if you did not receive a 1099-MISC with the income paid to you reported in box 7. When starting the SCH C if asked if you received a 1099-MISC simply answer NO and then the program will ask you for income not reported on a 1099-MISC, K-1 or any other document.
