Ask about Rule of 55. Empower customer support can help.
In simple terms, if you are 55 years or older and unemployed, by choice or otherwise, you can take funds from your 401k. There is no penalty. Taxes will be whatever state and federal you would have to pay anyway.
If you have Roth funds in your account, those funds can be taken with no penalty and no taxes since Roth is post-tax.
If you have both 401k and Roth, your withdrawal will be in the same split/% as those two accounts already exist in your fund. So, say you have 401k making-up 64% of your account balance, and Roth makes up the remaining 36%, your withdrawal will be 64/36 as well.
