powershell - Active Directory - Account exists but cannot find it to remove it

I'm trying to add an AD Managed Service Account and my first attempt was as follows:

New-ADServiceAccount -DNSHostName VM-Backup-Service -Name "VM Backup" -samAccountName VM_Backup -Path "OU=AD_Managed_Service_Accounts,DC=company,DC=local"

This command basically hung, I think because I pointed DNSHostName to something non-existent because I didn't do enough reading. I then tried to correct it and point it at the master DC using it's FQDN:

New-ADServiceAccount -DNSHostName AUDC.company.local -Name "VM Backup" -SamAccountName VM_Backup -Path "OU=AD_Managed_Service_Accounts,DC=company,DC=local"

The problem I have now is that AD says the account already exists:

New-ADServiceAccount : The specified account already exists

Which would be no big problem, if I could actually find said account in order to remove it before re-adding it correctly. I've tried tracking it down with:

Get-ADServiceAccount -filter 'samAccountName -like "*VM_Backup*"'

Get-ADUser -filter 'samAccountName -like "*VM_Backup*"'

And the following returns nothing, which implies there are no Service Accounts in the domain?

Get-ADServiceAccount -filter *

If anyone has suggestions for ways to track it down, it would be much appreciated. The only hints I have is that I know I specified the samAccountName in the commands above, and the snippet of the CN=VM Backup that is returned when it says the account already exists:
