Get your taxes done using TurboTax

A "backdoor" Roth involves a Roth conversion, not a recharacterization from traditional to Roth.  You did not "switch" your contribution from traditional to Roth.  Go back and tell TurboTax that you recharacterized $0, not $6,000 (or just delete the $6,000 entry where you are asked how much was switched).
