If you worked as an independent contractor and do not receive a 1099NEC you still have to enter your self-employment income and prepare a Schedule C. If you use online TurboTax you will need the Self-Employed version; if you use the CD/download you can use any version.

So if I received my money through checks can I still file the schedule c through TurboTax or does turbo give me a different form?
Yes still schedule C. Actually you can just enter it as Other self employment income or as Cash or General income. You don't need to get a 1099NEC or 1099K. Even if you did you can enter all your income as Cash. Only the total goes to schedule C.
