I've just gone through it page-by-page, and didn't see a table like that. Using the 20th Anniversary Edition, I also looked through the summarized list of claims in each chapter, and the 20-year retrospective, and did not see the table or a section that might have been a textual version of the same data.
Perhaps the closest bit I found was in the chapter "Plan One to Throw Away": "The total cost of maintaining a widely used program is typically 40 percent or more of the cost of developing it" (p 121). Similarly, another section quotes Capers Jones, "Focus on quality, and productivity will follow" (p 217, emphasis original).
That, I think, is about as close as MMM gets to these claims.
I couldn't find it either but in addition to "Code Complete" this data is also shown in a chart in "The Software Project Survival Guide", also by Steve McConnell (p29).
The attribution is "Researchers have found" but Boehm and Papaccio are listed in the references.
