I determined the only location with this issue was iTunes Media/Music folder, so I zipped up the entire folder to force symlink resolution. This worked to resolve the ghost symlinks (some had 4 hops noted but no source). Backups now run without error (-48 and 80??, I don't recall presently-8062).
OS X file system anomaly: "ghost '?' in file names and unexpected symlinks
I've never seen this before - only found it because Time Machine kept failing (on Mac OS X High Sierra 10.13.6). A similar question was asked here ~7 years go but it was not solved (and he did not have symlink issues): File names in OS X appearing with question marks
I ran disk repair several times from Disk Utility.app (which did not find or fix any errors).

What I've not been able to fix is the random '?' character in the file.
I tried the solution noted here: Remove question mark "?" from file names OSX which seemed like it would be perfect, but it had no effect. The "?" still persists even after the mv operation, specifically:
find . -type f -name '*?*' | while read f; do mv "$f" "${f//\?/}"; done
In Finder, no ? appears and you cannot grep "?" out of the name, so strictly speaking, the character does not appear to exist. They only appear in Terminal:
