This answer appears to differ from another Turbotax answer (Employee Tax Expert Vanessa A) to a similar question. Yours appears more cautious (which to me is good), but it's confusing to see 2 employees apparently recommending different approaches. She says "Since the tickets were bought for personal use and then sold at a loss this would be similar to yard sale items and not included on your return. You should still hold onto the 1099-K and proof of cost of the tickets since the 1099-K was reported to the IRS."
