I know exactly what you want and that the CDC shuffled things so it isn't apparent now. But I can't exactly lay my hands on it. There are a lot of things like that at this site: https://www.cdc.gov/nchs/products/index.htm. For instance NCHS Data Brief No.395 is about life expectancy and has death rates for age categories, but it's a pdf on my computer. You want data in the study by Genevieve Briand that was published in John Hopkins newsletter. https://www.jhunewsletter.com/article/2020/11/a-closer-look-at-u-s-deaths-due-to-covid-19
