Actually I would just enter your total income as Other self employment income or as Cash or General income. You don't need to get a 1099NEC or 1099Misc or 1099K. Even if you did you can enter all your income as Cash. Only the total goes to schedule C.
You can fill out Schedule C and enter 1099NEC, Cash or Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to the Premium or use any of the Desktop CD/Download programs. All the Desktop programs have the same forms, so you can buy a lower version. You just get more help and guidance in the higher versions.
