Business & farm

Thank you. I had already began working on my 1099-k info and added some expenses like supplies, etc but am not finding how to add money I spent to purchase the items I sold. I initially tried to add it under inventory until I realized that is not for items that have sold. I just knew it was showing my income too high and I can’t figure out how or where to input the cost of the things that were purchased. I did type in copy C and clicked on the jump to link but it immediately asked me about dividends I received….it’s very frustrating 😭😭😭
