You don't need to provide a business name if you are a unincorporated independent contractor, leave that field blank. Regarding the next questions, I would answer as follows;
1. Accounting method enter "Cash".
2. Inventory Method enter "Blank".
3. First Schedule C, "Checkmark on this box" as this is your first year!
Then proceed to enter the sales or income section, that is, the income received per the 1099-Misc and enter the appropriate expenses as considered necessary, ordinary and reasonable for your independent contracting business.
Hope that helps!!
