I have gains and losses for personal items I sold on ebay (about 400 different transactions for 2024) . I am reducing personal items that I have owned the last 60 years. I do not have a business or hobby, it is more like a online garage sale. I am retired and do not rely on sales. just trying to get rid of stuff. I do not have reciepts for cost base. Can I use the fair market value? Do I have to list every transaction separately? Where do I put the gains and where do i do the losses for reporting the 1099k?
