Business or personal income?

I have some audio albums that generate income (iTune, Amazon sales, radio royalties, click ad revenue from a website). I am not incorporated. The income is payable to me personally. I receive 1099-MISC forms for this income. I tiny amount of revenue was paid to my DBA, but that is me personally doing business as a fictitious name. So, when using TurboTax, do I need to enter these numbers as 'business' income or can I enter it as 'personal' income? Does it matter as far as raising/lowing my taxes? Is there some sort of self-employment tax that I may be unnecessarily paying by entering these numbers as 'business' income?
