Seems to be a conflation with the user-input shell history and the scrollback history of the terminal going on here.

I think original request was for the scrollback history.  Here's how to get that info...

(ins)sdowdy at carrotcake$ pstree -Alpsa $$
systemd,1
   `-konsole,23071 --separate
       `-bash,5456
           `-pstree,6513 -Alpsa 5456

so, our parenting konsole for this shell is PID 23071, check the open files with 'lsof'...

(ins)sdowdy at carrotcake$ lsof -p 23071 | awk '$NF~/konsole.*\.history$/{print $NF}'
/run/user/7771/konsole-k23071.history
/run/user/7771/konsole-G23071.history
/run/user/7771/konsole-C23071.history
/run/user/7771/konsole-s23071.history
...

If i go into the Settings:

    Settings->Edit Current Profile->[Scrolling]->  switch from "unlimited scrollback" to "No scrollback"

then check again:

(ins)sdowdy at carrotcake$ lsof -p 23071 | awk '$NF~/konsole.*\.history$/{print $NF}'
(ins)sdowdy at carrotcake$

as expected (no more scrollback history files).

Note that this directory is ${XDG_RUNTIME_DIR} (part of FreeDesktop aka XDG) which is where applications are supposed to keep their runtime non-persistent data.
It defaults to (on my system)  /run/user/{uid} (user id)

now, the bigger question...   these generally aren't user-serviceable parts, so what exactly do you need to do with them?
