The "[[#S132]]" and other links like that are Span IDs. The idea is that you can create a full bibliographic citation connected to that number and then you only need brief notes like a page number to refer to different points in that single citation.
They are an excellent way to create footnotes and linked citations...when they're done right. Unfortunately, a lot of early GEDCOM imports to WikiTree imported citations this way, but didn't import them correctly and a lot of information was lost during the import. Often it is impossible to figure out what the original reference was to and you just have to cut it and start over.
There are two "sources notes" that refer to that source (#132) and appear to be for a will and the estate inventory. I dug back through the change log and could not find that the full source was ever there to start with. But I don't think this case is hopeless!
In the middle of that profile is a subsection called "Biography Notes" that appears to be a wholesale copy of something written "by Linda Sparks Starr March 1999." Towards the end of that subsection, above its internal footnotes, the author says "Charles' Louisa Co. VA will is dated 9 MAY 1755 and was probated 24 MAY 1757."
My guess is that both the will and the estate inventory are in the Louisa County records. The will in Will Book 1, p. 35 and the inventory in Inventory Book 1743–1791, p. 46. You might be able to find them at FamilySearch and then write a proper citation for each.
