Was that meeting held in New York? Otherwise it would not be NY-source income and not taxable by NY.
If the income was NY-source, you're correct: you should still owe no NY tax (even though you'd have to file an NY return). TT should have generated a Schedule C or C-EZ when you entered the 1099-MISC with Box 7 income. On the Schedule C or C-EZ you would deduct the entire 1099-MISC amount as a travel expense, resulting in zero net income. Note that NY uses your total federal income to calculate your NY tax rate, but it applies that rate only to the NY-source income.
