I don't see how it's possible that this would be treated as taxable.
- Have you entered any other Forms 1099-R?
- Have you left box 2a empty on TurboTax's 1099-R form (as it should be on the Form 1099-R provided by the payer?
- Are you seeing the entry of this code T Form 1099-R increasing the amount present on Form 1040 line 4b?
- Or are you just looking at the refund display where the refund amount could be lowered by a side effect of distribution from the Roth IRA such as reducing or eliminating a Retirement Savings Contributions Credit that you might otherwise be eligible to receive?
