Do I need to file business taxes if I didn't make any money with the business? Do I file it with my regular Joint filing or separate?

I am currently using TurboTax Premier 2018.  I'm filing jointly, nothing too unique.  However, my wife and I opened an LLC in 2018 with the intent to start a business.  We did get the EIN with the IRS (think it was mandatory) and we got a form SS-4.  We did NOT actually start the business and did not make any money, and we have not intention to write off any of the expenses from establishing the business entity (like $500 or something). Do we still have to file with the IRS? If so do we do it with our normal Joint return or do we do a separate filing? If we do it with our normal return how? We'd rather just skip it all together if it's not necessary.
