airbnb shopper-where do my deductions go?

I help an owner with the cleaners of an airbnb, nothing to do with guests.  I schedule the cleaners and I shop(and pay for) for the cleaning supplies and the goodies we leave for the guests. They reimburse me for all these shopping expenses.  Lets says the 1099 shows $6000 for the year.  Lets say my actual wage is $3500 and all the stuff i bought is $2500.  Where do i report that $2500?  in supplies/business deductions?
