You have two choices, you can take RMDs starting with 2021 or you can distribute the entire account in ten years.
Of course, 2021 is over, but if you want to take the RMD option, you can take the 2021 RMD as soon as possible and take the 2022 RMD before the end of this year.
In that case you would file a Form 5329 to ask for the penalty to be waived. They usually accept that and waive the penalty.
Your son may have to file tax returns, to report the RMDs, depending on the amount of the distribution.
The next option is to do nothing now and distribute the entire account balance by the ten year anniversary of your mother's death.
The stretch IRA doesn't apply, because the account was not in your son's name prior to the enactment of the SECURE act.
