Unable to rip disks to Truenas server on the network

[Tonytitan]

This is me putting my ignorance on display.

I have a Truenas server for movies set up on my network. I am running Ubuntu 24.04 on my go-to PC. Sharing to my folders where the movies reside is enabled. No problem playing movies thru Kodi. When I rip disks saving them to the Truenas server is either not an option or I'm misreading what I'm being presented with. Unconfuse me, please!

If you take MakeMKV out of the equation, can you copy a file to your NAS via the same shared folder you're trying to use with MakeMKV?
