Can't Find Current Version of Server Files

I have a free server through Oracle Cloud that I use with my daughters. Everything works wonderfully, but due to a confluence of misfortune, I can't access my server through Pterodactyl. (I lost the password that was saved in a file and I can't get a password reset email from Pterodactyl.)

I have the password/SSH-key for accessing the server through Putty, but when I connect and try to transfer the files through Filezilla, I see the server in the state it was when I first uploaded to it. The version is 1.19.3, and the world is as it was back in April. I am connecting using the public IP and am in the directory listed as /home/ubuntu.

Any ideas why I am seeing the old files? Am I connected improperly? Is there any other way to get a copy of the current world? I've been very happy with Oracle, but I'm facing the prospect of losing months of progress. I'm not sure where to turn for help.

Edit: Solved! Thanks to timeactor for finding the correct folder where the instance files are saved. I had to give the user permissions to the folder through a Bash window, but I was able to access and download the world.
