I am self employed I got a 1099 for my independent work but in one marketing platform I earned for the year I have not withdrawn the money and I did not get any form.
Oh for self employment you have to report all your income even if you didn't cash it out. Was it under $600?
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.
