Why did my taxes go up after gambling winnings netted zero?...my losses were more than my gains, netting zero winnings, yet my federal taxes went up by approx. 1,000?

Gambling losses can only be deducted up to the amount of the gambling winnings.  Gambling winnings are reported on Form 1040 Schedule 1 on Line 21 as Other Income.  Gambling Losses are reported on Form 1040 Schedule A as a Miscellaneous itemized deduction.  Gambling losses are not a one-for-one reduction in winnings.  Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.
