Retirement tax questions

That is what I was thinking.  We sometimes think that what is sitting in my bank account is taxed dollars when in this case it has "CRD untaxed dollars in it "    I was able to talk to someone at IRS yesterday that poked into all the Knowledge articles on this as well..  her conclusion was similar - not perfect but indicated that it needed to go back into that Roll-over IRA to be counted as Repayment...   I am pretty clear that it can go back into another Qualified Retirement Account but it needs to come from the checking account from that balance of CRD pre-taxed dollars and not pre-tax employee contributions.    Thanks for the Validation.
