Thanks TaxPro+40...this is getting clearer. So, even if my 2018 purchases are for future book production and have nothing to do with current books that I'm selling, I should still enter that amount (which was about $2700 in 2018) in "Cost of Purchases"? Am I correct that expenses entered as "Cost of Purchases" should only be for production costs (design work in this case) for books that I may someday (in this case, 2020) keep in inventory? Not for expenses such as shipping boxes, tape, etc?
