The options for LLC type are S-corp, C-corp, or partnership. If you are not one of those, then it treats you the same as a sole prop. It should show your name as the Legal business entity if you are a single member LLC/Sole prop. I have a federal EIN and LLC, but I cannot use those in my Amazon tax interview. If you switch to an S-corp filing, I believe that will allow you to use your business name and EIN. If you are an S-corp, I believe you have to pay yourself a reasonable salary every month and it will likely have some tax savings also. I'm too scared to change mine and have issues with my account afterwards. I see all the horror stories about people changing bank, address, etc and having problems.
