Ok... Did you NOT save the SS-4 application you filled in at any time ? You had the option before you finished. Once done they give you the option to get the final paperwork buy mail or you could have downloaded it. That notice would give you the EIN & the information on what you need to file and when. If you choose the Sole Prop in error then you will simply NOT use that EIN for any reason. Start the SS-4 again and get an EIN for the LLC correctly if you insist on getting a number you have no need to have.
