When you say “matured” in an annuity, do you mean that the surrender period ended? Was it a MYGA – -multi-year guaranteed annuity that carried higher rates?
It’s impossible to answer your question of “how to invest” this money without knowing more about your total financial picture, risk tolerance, income needs.
One thing is sure, someone will be delighted to sell you another annuity– and earn a big commission, while locking you in for a period that could last 7 years or longer!
