Try not to rename it. Leave 'untitled' as label and rename it afterwards.

Are you booting to internet recovery? That's probably the best way to erase the SSD, assuming it is still good.
Boot holding the keyboard combination of Option-Command-R.
You will see a spinning globe during boot, rather than the Apple icon.

Try doing a SMC reset and then try the erase again.

Remember to disconnect from the beta of macOS 10.15 if you are interested on going release channel only - I think your computer will be activated for macOS beta despite a reinstall?! Someone can probably tell more about that.

If you want to get off the beta, that is.. I would, but that shouldn't mean you should too. There's shouldn't be anything hindering you in reinstalling macOS. The way to get a restore image of macOS Catalina is to download macOS Catalina 10.15.4 through the Mac App Store. That won't help you now unless you haven't totally gotten to erase your SSD yet, then boot back to macOS and download macOS Catalina - you won't have to sign in to Mac App Store to download the "Install macOS Catalina" app. Just search for it and click the Get button.

Depending on where you're deleting from, assuming that you at least have a chance to get to a Recovery Boot - use the Terminal on the recovery partition to erase and format the drive in question
Code:
diskutil list

Find the SSD - check the size in GB

Code:
diskutil eraseDisk JHFS+ Macintosh\ SSD disk0
or
Code:
diskutil eraseDisk JHFS+ Macintosh\ HD disk0

Code:
diskutil eraseDisk JHFS+ "Macintosh SSD" disk0
or
Code:
diskutil eraseDisk JHFS+ "Macintosh HD" disk0
- might be disk0 in your case - please check up on that.

you decide if you want to use the quotes code or the back slash. That's why there's two similar sounding commands.

If there's no way access any other Mac - look into getting on a Windows computer and see what tools are available for making a solid macOS install of Catalina on USB.

I think you need to completely dismantle the APFS partition for this to work better for you. Try opening the Terminal and type
Code:
diskutil apfs
and try the
Code:
diskutil apfs deletevolume
or
Code:
diskutil apfs erasevolume
code


what are the details of the error? if you click the little arrow or press spacebar in that window? Perhaps unmount the disk beforehand.
I believe the ones giving you grief are the Macintosh HD - Data and such.

Edit... Or
Code:
diskutil apfs deletecontainer
I think that's it - now that I tap into my memory

Code:
diskutil apfs deletecontainer disk0
You'll notice that disk0 is what your SSD is. That's why I typed it out. Terminal is available in the Utilities menu of the Recovery Partition

I hope you have backups of all the stuff :)
