Get your taxes done using TurboTax

You are able to file a Schedule C without a payer's EIN or a 1099-NEC. When you are inputting information for your Schedule C, click on the option Other self-employed income under Common Income. This includes cash and checks received and income not reported on any particular 1099 form. 

You will only have to enter the type of income (example: cash) and the amount for your Schedule C.
