Change Business Code when filing taxes

Hello! 

 

I have entered all the expenses and income for my business but the business code is wrong.  It is putting me in the wrong business code and service type.  

 

I have searched everywhere trying to figure out why there is no edit button under business code and all the answers I see online are not helping me. 

 

How do I change the business code number to the correct one I want?  This is becoming very frustrating.
