Why do I have to complete questions asking about a business I do not have? Received a 1099-NEC as a non-W2 employee. I was expecting a 1099-MISC.

The 1099NEC is the new 1099MISC for self employment.  It replaces the 1099MISC.  

Yes you are the owner of your own self employment business. You are in business for yourself. Use your own info. The people or company that pays you is your customer or client. You need to fill out schedule C for self employment business income. You are considered to have your own business for it. YOU are the business.

To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax. You can fill out Schedule C and enter Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to Premium version. Or buy any of the Desktop programs. All the Desktop programs have all the same forms, but you will get the most help in the Home & Business version.
