"I started a job some time ago, than the boss 1099'ed me. She told me to start a business which I did, but she's pays me by my personal name not my business name.

I received a letter from the IRS asking me if I'm a business and what do I do for the company I work for. I'm scared to death since I started seeing stuff on the net about having to pay quarterly taxes, etc. I have no employees, I sell nothing. I just created a business name so I can get paid.
