529 Rollover to Roth IRA - Where to enter?

We withdrew $7000 from my son's 529 account & received a Form 1099-Q that shows the distribution.

The form reports the amounts that are basis and earnings.  I entered the Form 1099-Q information regarding the $7000 distribution, but where do I enter the information that we rolled over to a Roth IRA so that Turbotax does not count the earnings as taxable?
