Clients 529 is eligible for Roth rollover.  Account value is $40,000 with $25,000 in basis and $15,000 in gain.  If we do a rollover to a Roth IRA, $7000 per year, is that comprised of both basis and gain until the $35,000 is used up? So that would leave about $5000 that is comprised both basis and gain?  Or is the basis rolled into the Roth leaving the $5000 as all gain?  If each year is both basis and gain then would the 1099Q show what is gain and what is basis?
