Stubhub/ TM fan to fan resale on taxes(i had a few extra concert tickets that I was unable to attend and sold them for a $937.45 gain, where should I report that?

[shellbo6987]

I don't have all the dates of purchase or sell dates, right now I have each of  them in Total Miscellaneous Taxable Income, so I put in the total amount of money I got for the tickets in 2018, but not the difference from what the ticket costs to begin with.

Is there somewhere I can put this that had the total costs paid for them in 2018 or just the total gain. I've looked into putting it in sch d also, but again that needs to know purchase dates and sale dates.

I just had 12 concert tickets that I bought months before they were happening and my plans, work, other responsibilities made it so I couldn't attend)

Or can I put it in as a hobby income, because then I can put the total amount I got back as the income and minus my gain to get the hobby expenses?
