The IRS requires you to report any income, however minor. Having said that, when an employer "cashes out" an 'employee' after a very short term of employment, no W-2 is issued to the 'employee' or reported to the IRS. 

If you try to report it as  Wages in the "Other Income not already reported on a Form W-2" interview (Other Common Income > Miscellaneous Income) the program will require you to prepare and file additional forms (Form 8919 and Form SS-8) that will serve no material purpose given the amount involved. 

You can, however, report the payment in the "Other reportable income" interview  (Other Common Income > Miscellaneous Income). Given the amount and duration involved, it is reasonable to argue this payment was not related to your "main job" but is more accurately described as "Casual Labor".
