Most of us don't pro forma til January after a few releases/bug fixes.

I can understand that. We like to use the new software to do our year end tax projections, but we have to rethink that idea. As it stands now, we will need to enter zip codes for all our tax clients (no small task) or re-import over the work that we have done (more likely option).

There is an old saying - "the early bird gets the worm".  That saying does not apply to Intuit.  Only bad things seem to happen to folks that transfer clients early.

At this point I only proforma a client at a time to do planning. In your case, I would delete all 2021 clients (maybe except for the one your are working on) and then proforma others as (a) you absolutely need to or (b) when the program finally gets sorta stable in late January.
