The Miles Files do show Edward Turner https://espl-genealogy.org/getperson.php?personID=I26033&tree=1 independently, with a note under "Anecdote" matching the one for John Turner. This indicates that they were relatives, but does not show exactly how they were related (possibilities include uncle and nephew, cousins once removed, or more distant male-line connections).
The "Anecdote", identically worded on both profiles:
A yDNA test revealed that the Genetic Distance between Stephen Wayne Turner (b 1945), a proven descendant of Samuel Turner I (c.1672-1760) of Worcester Co, MD and Brendan Turner (b.c. 1985), a proven descendant of Edward Turner I (c.1670-1729) of Northampton Co, VA is 6 at 37 markers and 7 at 67 markers. This is consistent with them being descended from a shared ancestor who lived in the late 16th century or early 17th century before coming to the Eastern Shore of Virginia. Their yDNA is shown as "salmon." (yDNA analysis provided by Nigel Bond, a member of this "salmon" yDNA group.)
Samuel Turner I is explicitly shown as son of John (hus of Sarah Kellam) Turner.
This is another of those frustrating cases where "yes, they are related in the male line but we don't know how" and may never know.
