Self employed Llc

I am self employed.  I am the only owner and my business is an LLC.  I filled my personal tax return already but did not include my business at all.   I also paid myself from my own business.  I also held a job that issued me a W2.  I'm not sure if I need to amend my personal tax returns to include my business income or should I file my business income separately? Any help is greatly appreciated.
