Just started a new business and don't know where to start

Hello,

 

I just started a brand new single member LLC as a health coach. Where can I find information on how I keep track of everything and how to pay taxes? I'm completely new to starting a business and all that is required. I have not yet started making any income, but plan on it very soon.  Does it matter if this is a side-gig instead of my main source of income? Thank you so much
