Sounds like you made an incorrect choice (or several incorrect choices) somewhere along the line in the application.

I just started an application, chose LLC and 1 member and the very next screen showed this...do you remember seeing this first page?   then the next page it asks why youre applying..did you choose started a new business or what?

A single member LLC is generally disregarded, and reports on F 1040.

You evidently answered some of the questions incorrectly, and now the IRS *will* expect to get a partnership return.

Edit...my comments below is uncalled for; I didn't realize @jasontran IS a tax pro.  Mea culpa

I suggest you seek local, professional help with rectifying the situation. 

This forum is for tax pro's to assist other tax pro's.

I think you should call in Monday morning and see if you can get that EIN voided or canceled, explain that this wasnt as intended then try again.

For questions relating to business accounts or failed EIN requests, call the Business and Specialty Tax line at 1-800-829-4933. TTY/TDD: 1-800-829-4059.

Anna, jason posted earlier, I think he is a new preparer, not a DIYer.  

Thank you.
