Turbotax online help "What is the difference between a conversion and recharacterization" states " ---- Tax rules allow taxpayers to recharacterize their IRA contributions any time prior to the due date, including extensions, of their tax return. A recharacterization allows you to undo or reverse your rollover or contribution."
However, my financial institution says can only recharacterize "contributions" not "roll-overs". Is clear that law no longer allows Roth to IRA recharacterizations, but less clear as to IRA rollover recharacterized into a Roth IRA.
