My Roth distribution was 100% from contributions. I should not have to pay any tax. How do I tell turbotax this?

The only way you would have taxes associated with a Roth IRA distribution is if it was an early distribution (before age 59 1/2) or the funds were not held in the account for five years. Without knowing what amounts you have in the boxes on your Form 1099-R, it is difficult to be more specific than that. I suggest you revisit your Form 1099-R entries and answer the questions again with those facts in mind. Also, the codes in box 7 will help you determine how the distribution will be taxed. Code J would indicate that it was an early distribution on which the earnings would be subject to tax and penalties.
