For starters, you may want to contact a financial advisor (one who does not sell investments) and have a long chat about retirement.
I have not read all the posts, but you need someone who can do some math for you.
In your first post you do not say your age nor if you are married (or if there is any likelihood of marriage in the future). Those leave big gaps in important information.
People are living longer and longer. Some are doing quite well in “old age” and some not so well. You don’t mention anything about any relatives (which can be a bit of general information as to how old you might live to.
Some things you should address with the advisor: health care issues; retirement issues such as what you might want reasonably to do in the future; how long you might be projected to be in good health and for how long in retirement; what happens if you move to a retirement facility and what projected costs might be like for that; what projected costs might be if you have to go to an assisted living facility, and how long you might be in one until death.
You also might inquire about the various types of insurance and insurance related products, such as annuities; ;and make sure the financial adviser has experience and training in this as some are great, some are good, and some not so good.
Not knowing your financial condition, it may be that after retirement you might want to travel some, including the possibility of going on one or more pilgrimages, for example, to the Holy Land. careful administration of your current retirement funds plus some of the suggestions herein might make that available; - and last I recalled, no one suggested that was less than pleasing to God.
And ultimately you may have the ability as part of financial planning to contribute, as part of your estate, to various works of charity or to education.
You have been blessed with an opportunity. Getting a good non-selling financial planner, and a good attorney is my best advice.
