Sorry to be blunt but if you don't know the answer to that question you need to RUN to a local tax professional to get educated on what you have done ... if you did get the EIN from the IRS as a multimember LLC then the issuance notice told you to file a form 1065 as a partnership which was due 3/15/21 (even if you have no income to report) so not only do you need to file a form 1065 but you also are very late in doing so and the penalties are adding up fast... $205 per member per month. Seek local professional assistance ASAP.
