Your will does not control your 401k.
Retirement accounts and life insurance pass by beneficiary form. That form is a contract with the company holding the money. It does not read your will and it does not lose to it.
So the line in your will leaving everything to your spouse does nothing to the account where you named your mother in 2011.
Log in. Read the name out loud. If it surprises you, that is the point.
