I started a business in 2023 I filed my personal taxes and not my business taxes when I filed. I have been ripped out by so many companies. How do I file 23-24

How is your business set up?  Is  it a sole proprietor/self employment that you need to file on Schedule C in your personal tax return?  Or is it a separate Business entity like a Partnership or LLC or corp or a Single Member LLC set up as an S corp?  You need to file a separate business return for those.  

If you need to file Schedule C for self employment  you need to amend  your returns to add it.
