How can I add a second business code to my self-employment?

I am a music teacher & performer. Because many of my expenses overlap, I am filing as one business and require two business codes. Turbotax will only select one code. How do I add a second code?

Create two Schedule C’s for your separate businesses and split expenses between them according to your best judgment of how much each expense is attributed to each business.

I don't think the business code is necessary.  It's just for statistics.  You can enter any code or even 999999.  I wouldn't worry or bother about it.    The 2 things  you do are pretty similar and in the same area so I think you can combine them.   It's not like you are a music teacher and a plumber.
