Used bootable USB drive to start (Was running Mojave 10.14.6). Also had external drive with backup of old internal drive. Disk utility only recognized the external drives. Did the Command-Option-R boot and got the Internet Recovery system which ran for a while but no change.
Is this a good question?

Make sure new drive is securely seated into the drive port and secured with proper screw.
When you boot from external and open Disk Utility, go into the upper left “view” button and click “show all devices”. See if your internal shows up then.

Yup I have the same problem, I end up installing the original SSD from Apple. this problem happens when I accidentally locked my MacBook from find my and erased the entire SDD from OWC Aura Pro X2 SSD that was installed and running the latest MacOS Big Sur.
However when I want to reinstall macOS big Sur into OWC Aura Pro X2 SSD, my MacBook does not detect the drive. it feels like when i erased my MacBook data from Find My app on iPhone, it deleted the entire OWC Aura Pro X2 SSD which causes my MacBook not able to detect OWC Aura Pro X2 SSD presence when trying to reinstall the recovery mode. disk utilities doesn't detect OWC Aura Pro X2 SSD. Im out off options now and felt like I should give up and throw OWC Aura Pro X2 SSD away!!

Can you boot regularly from the internal drive?

@mayer Yes. It boots and I can bring up MacOS Utilities but when I try to use Disk Utilities as you had suggested in a previous dialogue, all I see is "macOS Base System Disk Image Volume - Mac OS Extended macOS 10.15.3" which describes the 2 GB external USB drive that had the boot drive with Mojave OS. I get that now even though that drive is currently disconnected.

When I say it "boots" from the internal drive, I mean that ALL I get is the macOS Utilities screen - nothing else.

Correction: I shut down the computer, removed the external drive and then rebooted. Would NOT boot. Displayed picture of a file folder bearing a large question mark and nothing else happening. Will try to physically reinstall the SSD tomorrow just to be sure. If the new SSD needs to be formatted first can you tell me how I do that?

Use Disk Utilizes from the external drive to format the new internal drive. Use the plain APFS format if you can. Now install your system and boot from it. Don't be surprised if you can no longer see the external drive, you can still use Migration Assistant to move your user and APPS. If all this fails, just wait, I order the same drive today to go into the same machine, so I will be doing the same thing within the week.
