You didn't get any form? No W2 or 1099Misc or 1099-K, etc?
Just enter it as Cash or General income. You don't need to get a 1099Misc or 1099K. Even if you did you can enter all your income as Cash. Only the total goes to schedule C.
You can enter Self Employment Income into Online Deluxe or Premier but if you have any expenses you will have to upgrade to the Self Employed version.
