It's doubtful that TurboTax is including this in income if you entered the Form 1099-R correctly because TurboTax is programmed to exclude the amount from Form 1040 line 4b where it would otherwise be reported. Where do you see TurboTax including this amount in income?
The only possible way that I can imagine that a code-Q Roth IRA distribution would have any effect your tax liability is if the distribution from the Roth IRA had the side effect of reducing the amount of a Retirement Savings Contributions Credit that you (or your spouse) would otherwise be eligible to receive.
