Congratulations!
Hopefully, you use a retirement planner that is a fiduciary advisor that has very low annual cost and that has you in low-cost funds.
Check out the bogleheads.org forum if you want to get into the weeds on this some. That site has a wide cross-section of investors, from people just getting started on saving, to retirees with just a little saved and also those with millions. Topics are investments, personal finance, and consumer issues. I hit that forum and this one every week at least.
