I'm still not sure what happened at this point.  Either you have a corrective distribution or you have a recharacterization.  If you're saying Fidelity will issue a 1099-R code R then you have a recharacterization and you'd just report a $6K contribution to a traditional IRA, which will either be deductible, or non-deductible, or perhaps excess if there is no earned income.  The earnings would need to be transferred as part of the recharacterization BUT they're treated as if they were earned within the traditional IRA (so tax deferred until withdrawn.)

So we really have to circle back to Michelle's point:  Ask them where the money went.
