I assume you don't have to pay the money back, so it would not be a loan. That being the case, it would likely be considered a dividend by the IRS since it came form a C corporation. You could enter it as such in TurboTax, using a From 1099-DIV entry, Your other option would be to report it as "other income" by virtue of the form 1099-Misc entry in TurboTax. If you do that, indicate that the income was not earned in the prior or next year, that it wasn't associated with your main job and you didn't have a profit motive to receive it. That will result in it being treated as non self-employment income.
