You must be getting 1099-MISC income. This is income paid to a contract worker, meaning you are not paid by an employer, are self-employed.
If you do not claim any expenses, you can file a simple C by using TurboTax Deluxe.
If you do claim expenses, you need to use the TurboTax Self-employed software.
This should not cause an issue, you can always start in TurboTax Free and progress to the higher version if needed.
