The Online version does not have the Forms Mode. So the answer above won't work if you are using the Online version. I would forget about entering the 1099NEC. Just enter the total as Other self employment income or as Cash or General income. You don't need to enter each 1099NEC or 1099K. You can enter all your income as Cash. Only the total goes to schedule C.
