I want to partition the SSD into 2 Drives, but Disk Manager will not allow me. The "+" is dimmed, and it says the size can not be changed. I can transfer files to the new SSD, OK, so it seems to be working OK. What am I doing wrong?

What format is the SSD, NTFS? You may need to erase it and pick APFS or HFS+ first, then you could partition it.
If you format it APFS, then you don't need to partition it anyway, you can just add extra APFS volumes in the same container.

Partitioning using "+" option on disk utility greyed out on my MacBook running macOS Sequoia.
