You don’t need to go back to the initial questions. You can just add you business on Schedule C. I assume you need Schedule C for self employment income.
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.
