What is a MEGA BACKDOOR ROTH IRA contribution?

This video explains in detail what the Mega Backdoor Roth IRA contribution is: a way to bypass the contribution limit on Roth IRAs (which is $6,000 in year 2021) and stash even more of your cash away in a tax advantaged account.

These after-tax contributions are not subject to the normal contribution limit ($19,500 in 2021). In fact, you are allowed to contribute up to $58,000 using this special type! Then to perform the mega backdoor Roth maneuver, you take an in-service distribution of your after-tax 401(k) money and convert it to a Roth IRA.
