You're going to report the second part of the COVID withdrawal from your IRA on form 8915-F. That should be available in the TurboTax software on March 17th.
How you're going to handle the accidental return and withdrawal of the 81K to your retirement plan will depend on how they plan documents it. If they send you a 1099-R for the withdrawal you should be able to show it as not an actual withdrawal. But hopefully they will simply regard it as a removal of a contribution and not send you a form for it for 2021 at all.
