code and just include the overall income.. I notice that if I use different code I need to put in expenses separately which is doing the same thing twice? Or for the second code should I by pass all of the expenses?

If you use multiple codes for different business, you would only have to put the expenses related to the code/business for each.

If you only want to use one code, you would have to find the code that best describes your business, or at least your main business.
