"However, I don't see that the text you pointed to says I'm grandfathered."
SEC. 401(b)(1) of the SECURE Act explicitly states:
IN GENERAL.—Except as provided in this subsection, the amendments made by this section shall apply to distributions with respect to employees who die after December 31, 2019.
This means that the SECURE Act has not changed anything with regard to your RMDs. The only thing that has changed since 2002 with regard to your situation is that for 2022 and beyond the IRS has issued new life-expectancy tables which require you to recalculate your life-expectancy factor from on the new Single Life Expectancy table based on your age in 2002, reduced by 1 for each year after 2002. This generally results in a slightly lower annual RMD than the amount based on the old life-expectancy table. If your IRA custodian is doing the RMD calculation for you (and they are competent), they will have already done this.
