Gambling winnings are taxable income.  Losses are an itemized deduction.  If you do not have enough itemized deductions to exceed your standard deduction, your losses will have no effect.

"Is it better"?

The simple answer is to enter everything and let Turbotax pick the best method.   If you don't already itemize (because your normal itemized deductions are less than your standard deduction), adding gambling losses might push your itemized deductions higher than the standard so you would save some money by itemizing.  But Turbotax does these calculations for you.

If you are married filing separately, whether you choose itemized or standard deduction could affect your spouse's return.  But if you are single, married filing jointly, or filing head of household, then just let Turbotax pick the best deduction for you.
