"since it has been over the 6 months it can not be done. "
There is no definite time limit imposed by the IRS. Section 3.02(3) of Rev. Proc. 2020-46 says:
(3) Contribution as soon as practicable; 30-day safe harbor. The contribution must be made to the plan or IRA as soon as practicable after the reason or reasons listed in the preceding paragraph no longer prevent the taxpayer from rolling over the amount distributed (which includes any amount withheld for income tax) or a lesser amount if the taxpayer wants to roll over less than the total amount distributed or if part of the amount distributed is ineligible for rollover. This requirement is deemed to be satisfied if the contribution is made within 30 days after the reason or reasons no longer prevent the taxpayer from making the contribution.
I would not consider it practicable to complete the rollover of the funds from the designated Roth account to the Roth IRA until the funds had been distributed from the traditional IRA account where they should not have been deposited. 30 days is a safe harbor, but there is no definite time limit.
