I give all credit to the following page/author where I leave out a few steps and embellish with some details of the install.
SSD FOR MACBOOK PRO 2012 RETINA INSTALL
You do not need to download or install any patches, Catalina runs on this model.

Use lesniakrafal method with GPT assigned and EFI partition included on the raid0 array virtual drive, I did get a successful install with updates. This runs but updates failed for me so diskutil list should show an EFI partition on disk2. One using the Disk Utility to create the array and end up with a virtual container with no GPT or EFI partition. You can get a successful install on /dev/disk2 the virtual drive 2 ways.Install to external drive, resize with diskutil apfs resizecontainer disk4s2 499400m, and dd back does work but again system updates and installs do not work without running csrutil disable from installation usb.This might be useful if you want to copy your current install and possibly you could get updates to work normally using the method I present here after doing a resize. dd if=/dev/disk5 of=/dev/disk2 bs=64k where disk5 was the synthesized external install and disk2 was the (virtual raid). Problem was I had dd'd a 250GB drive to external 2TB with dd back resulted in a 250GB on a 500GB raid0 array. I did manage to install using unix style dd and seem to remember I could do updates, install problems can be overridden with xattr -cr or running csrutil disable from installation media.I did try ccc and was not able to do updates or installs.Please forgive if I stumble around, I have 25 years using unix but this is my first Mac I got 3 weeks ago. I tried several methods since lesniakrafal did not work directly on my first attempt but after several attempts this does work.
