The questioner is talking about tmp in the user directory instead of /tmp. From the directory you listed above, it seems that it may be apt cache. You can execute the command sudo apt-get clean to clean it up, and then you can see that the directory is smaller. without.

Never touch /tmp if your system is running any meaningful tasks.
But if the things in /tmp linger for a long time, appear every time you restart, and will not disappear automatically, then I don’t think you have to be dogmatic about “/tmp must not be moved.”
If these few Gs are really important to you, then please be prepared before you start: ① Turn on the computer; ② Use root privileges to delete them all at once; ③ Restart immediately.
Tell me about my experience. I once used a cPanel virtual host. For a while, I frequently encountered the problem of file upload failure. Detailed analysis found that the program was correct. The problem was that the disk was full when writing to /tmp. cPanel showed that the usage of /tmp had reached 100. %.
The virtual host has limited permissions (not even SSH). As a result, there happened to be a typhoon on the southeast coast in those few days. Unfortunately, the host company was fleeing the disaster and could not be contacted at all... So I had no choice but to make a high-risk one. The thing is, use a php script to remove all the things in /tmp that I have the right to delete. As a result, the /tmp usage returned to 3%, uploading immediately returned to normal, and the operation has been uneventful so far.
