Most of these are free drops under 1m, but need decisions on following. Since you have no remaining cap in 2020-21 you can buyout starting with this season (2021-22).
D Justin Holl, $2.0m (2022-2023) - Over 26 years buyout:
4m total at 2/3 = total buyout 2.7m
Let me know what amount you want to allocate to 2021-22 and what you'd like in 2022-23
C/LW/RW Jeff Carter, $5.3m (2021-2022) - Over 26 years buyout:
Guess not much decision here 1 year left so total is 3.5m on 2021-22 books
