Gambling losses not handled correctly on form 1040

I had Gambling winnings I entered with W2-G.  My tax burden increased as expected.  I completed the questions and entered gambling losses which should have reduced my tax burden (only that portion that was increased by the gambling win).   The tax burden remained after entering losses with only minimal adjustment.  It should have been almost completely eliminated as my losses were almost equal to winnings.  To prove this out, I created a new tax return and did not enter gambling winnings and losses, recorded all values.  I went back in, added the winnings, noted the tax burden increase with each win.  I then added the loss and found it only reduced the tax burden by 1 of the win amounts.  I downloaded form 1040, Sched A and Sched 1 instructions along with form 1040 and ran the numbers manually and then called the IRS to confirm that based on the amount of my wins and losses, I effectively should only owe taxes on the other portions of my income.  How do you report issues like this to Turbo Tax for resolution?
