Turbo tax asking me: Do you use your name or another name for your business? SMLLC disregarded entity etc?

You need to decide which you are going to use, your personal name and social or your business name and EIN. Why do you have an EIN to sell items on the internet. You can use your own name.

Thanks! Yes, I used my personal name for years on one website and then I started an LLC to use a business name. But then I also sell on Etsy and they wouldn't let me switch to my new business name, and I didn't want to lose the feedback on my account by switching so that's how I ended up with both. 

So I just put my Social and my EIN both on my Schedule C. 

It's not ideal yes, but Etsy is very stubborn with their shop names and usernames .
