Retirement tax questions

Dmertz, amazing explanation!

Thank you again.

I have a better understanding of the formal mechanics involved.  I say “better” but not complete.

From my simplistic perspective, I expected a rollover from a 457(b) Roth to a Roth Contributory account to be an Apples to Apples transaction, the 5 year holding period having been met by the one account would transfer to the other.

Cheers Indeed!
