Question Regarding Class Action Proceeds for a Retirement Account

Hello,

 

I received a class action check the other day due to a settlement from a former employer retirement account. The check has already had 20% federal taxes withdrawn. I will be receiving a 1099-R as well. Would I be able to deposit the check to my 401k and receive back the taxes paid out? Should I expect to see additional taxes or penalties (like early withdraw penalties) when I deposit the check? 

 

Thank you.
