You cannot include your daughter's 1099-K or 1099-MISC income in your tax return under any circumstances. If she is required to file a return, or if she files even though not required to, the income has to be reported on her tax return. If she is not required to file, and does not file, the income does not get reported anywhere.
However, it's probably a good idea for her to file a return even if she is technically not required to. The 1099-K from Ticketmaster will show the total amount that she received, not the amount of profit. If she doesn't file a tax return, the IRS doesn't know how much she paid for the tickets. They will assume that the amount on the 1099-K is all profit. If it's $400 or more, they will think that she was required to file.
Whoever paid the "small cash prize" is not required to issue a 1099-MISC if the amount is less than $600. So if she gets a 1099-MISC, the amount is probably $600 or more, and again, the IRS will expect her to file.
Even if the 1099-K and the 1099-MISC are each below $400, the IRS will expect her to file if the total of the two is $400 or more.
