Are you a Single Member LLC? Are you an S Corp? A Single Member LLC that is not an S corp files it on Schedule C in your personal tax return. It is a disregarded entity an filed as self employment.
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.
