I started a dba this year under my original llc. Both the llc and the dba earned income. Do I file it all under the same company?

Under self-employement income it states the 'line of work'.  The original business is listed with the EIN.  Do I add the dba as another 'line of work' or do I just add the expenses under the original llc?  I don't have a unique EIN for the dba business.  It's the same as the parent llc.  Thanks!!
