Should we add a small income from music streaming services for our 14 year old son in our return? how to handle that?

It depends. You have to report all income you earned during the year on your tax return. If it was your 14 year old son's earnings, then you would report that on his return.  This small, side income is reported on a Schedule C (self-employment income). If the total income is below $400, then you would not have to pay self-employment tax on this income, but it is subject to income tax. 

For tax purposes, self-employment income includes any part-time businesses or "side work" performed in which you are in business for yourself, rather than another person. You are also considered self-employed if you engage in business-like activities where you intend to make a profit. 

Please follow these steps in TurboTax to start your Schedule C:

1. Open your return.
2. Search schedule c with the magnifying glass tool on the top of the page.
3. Go to the Jump to schedule c link in the search results. 
4. Answer Yes to the page titled, Did you have any self-employment income or expenses?
5. Follow the on-screen instructions.
6. On the page titled Let's enter the income for your work, click on Other self-employed income under Common Income.
7. Enter your type of income (cash/check) and the amount.
8. Follow the on-screen instructions.
