A client, age 40, has been contributing to a Roth for 21 years.  He has made contributions over the years totaling $26k.  He recently withdrew $34K which would be the original contributions plus earnings.  The original contributions are not taxable but the earnings ($8k) are.  The 1099-R shows the Gross Distribution of $34k, blank Taxable and Code J.

What is the proper way of inputting it so only the earnings are taxable? The distribution is not qualified.
