IRA

I am 71 right now and turn 72 in January 2024. I have an IRA account and I believe I need to start taking withdraws next year when I turn 72.

First is the age correct?

Then how much do I need to withdraw?

Do I have from my day turning 72 to December 31 to withdrawn the required amount?

My account is currently way down because of stock loss. Does that make any difference?
