Any of the money you will need in the next 6 to 12 months should be held in a money market or savings account.
For the remainder of the inheritance it would be appropriate to have a financial plan created or updated with this information. It will give you the opportunity to map out your retirement goals. Then this money can be invested in the proper investment allocation for your goals and risk tolerance.
