Turbo Tax online will not allow me to edit my business code. Parts of Sched C have a blue pencil, the business code does not. I need to correct mine. Any suggestions?

TurboTax Online will help determine what business code you should use based on the information that you have entered in the Work Description under General Info for your business.  As you edit and change the Work Description, the business code will change as well.  You cannot edit the business code directly.
