Where does uber income go in self-employment tax?

I've already entered my 1099-K UBER income in the 1099-MISC area of the "Business, Income, Expenses" subsection, and wrote in the deductions for all their fees (not sure I did it correctly) in the other/general category in this same subsection.  The fourth subsection down is "Business Taxes" with a category for "Self-employment tax." When you click that you can choose the third option, "Self-employment tax." I'm assuming I must do this section since UBER is considered a small business. Is that right?

However a note appears saying, "Currently you aren't required to pay self-employment tax." Is that because I made less than $600? I only made about $488.

Thanks for your help!
