Did the CARES Act also have an impact on retirement account distributions?

Yes, it did. The CARES Act waives the RMD rules for certain defined contribution plans and IRAs, but for 2020 only. The result is that, whatever your age, you are not subject to RMD rules this year. You can still take distributions, of course, and they will be subject to income taxation, but you are not required to take a distribution.
