I don't know what you mean by "gambling records". You would have 1099-G for winnings over a certain amount, and your own self-declared losses.
If Turbotax made a mistake, turbotax is supposed to cover any interest and penalties, but you always owe your own correct tax. You have to file a claim within 30 days of the notice of deficiency.
