Photography Biz

I started a new photography business this year.  The local high school has hired me to take player photos of each of their teams.  I take the photos, edit them and then have packages printed that are ordered by the parents.  They pay via Paypal or Venmo.  I order the prints from a professional print shop and pay for the prints and sales tax.  How do I report this on my taxes.  The whole photography income thing is new to me.  I should also say that I am not paid by the school for any of this.  What I earn is just from the profit of taking photos and selling packages based on the orders.
