Smartctl tells me the problem is at LBA 2014551336 (this is a 2TB disk).

I'm not able to determine what file might be sitting on this block.

This suggests that the problem is not in a currently extant file.
I'm now trying the suggestion of writing from /dev/zero to a file in
/home while in single users mode. Given that I have 1.5TB to fill,
this could take a while.
Here's the question: If I just reformat and restore /home from a
recent backup, will the disk automatically deal with the sectors
pending reallocation?
The pending sectors will be reallocated only when they are written to. Unless
invoked with the very slow "-cc" option, mke{2,3,4}fs will write only to the
metadata areas, and restoring /home will of course not write to any remaining
free space.
