you are fine; those new 10 year rules you reference were only for deaths that occured on or after Jan 1, 2020.
you are grandfathered in under the old rules....
look at the very top of page 11 - the first sentence in italics
https://www.irs.gov/pub/irs-pdf/p590b.pdf
The 5-year rule generally applies to all beneficiaries if the owner died before 2020. It also applies
to beneficiaries who are not individuals (such as a trust) if the owner died after 2019. If the owner died after
2019 and the beneficiary is an individual, see 10-year rule next.
so the new 10 year rule affects deaths 'after 2019'.
