Don't know if ever had an 401k different emplorers

Can you check my 401k

I'm of retirement age

First, its not a good idea to piggyback your questions on other threads. I've merged all your posts into one thread of your own.

We can't check your 401(k). You have to contact all your former employers to see if you have any. However, you should have been getting, at least, annual statements from them if you had.

Also, since you are of retirement age, have you applied for Social Security? When you do, they should inform you of any corporate pension benefits due you.
