Had same situation, although it was a 2018 return, and yes, you will have to do a lot of overriding    

Here is what I overrode .. your situation may be different

1. on each shareholders K1:  beginning and ending date
2. on each shareholders K1:  all amounts in Part III
3. on K1 worksheet:  ownership percentage for period of ownership  (was only way to get it to flow to the K1 )
4. Schedule K reconciliation columns for 12a, 13g, 15a, 16c, 16d  (may be different on 2022)
5. Weighted average ownership percentage worksheet:  Shareholders percentage

Don't forget to attach the 1377 election and include the election verbiage at top of each K1

I'm sure that's not covering everything for a 2022 return but it gives you an idea.

Good luck
