First time my doing taxes!

I’m doing my taxes soon for the first time with my Amazon business. Normally, my tax person for over 30yrs has done good stuff for me and filling in some fields for me and such. This year, she is asking for my expenses and sales for 24′. I am not sure what can be expenses. I do have QBO and a biz checking account as well.

I’m looking for help on what I could use for expenses, obviously inventory, memberships, re-occurring debits. What else could I possibly claim? Thanks and much appreciated.
