Your RMD is calculated by each of your tax advantage accounts. So if you have a regular IRA (not a Roth account) the brokerage account will calculate the RMD for that account. If you have multiple accounts each account will calculate and report the RMD for each account. You are required to withdraw that amount from the account each year.
The RMD is calculated using IRS table on life expectancy. Table III for an 80 year old person is 20.2 . You would take the value of your IRA account (each account separate) on Dec 31, 2022 and divide by 20.2 For example if you had an IRA with an account balance of $100,000 on Dec 31, 2022 you would need to withdraw at least $4,951 from that account (100,000/ 20.2) The RMD should be on the forms your broker sent you. If you have any questions pleases call your broker or the company managing your account (such as E*TRADE)
Hope this helps
