Hi there, @usersobeckwoodcraft.
Allow me to share some details about the QuickBooks Self-Employed user management access.
This QuickBooks version is only available to one user. Also, you've mentioned that your business type is Partnership which means that you need to set up separate equity accounts to track investments and profits it properly. I'd recommend upgrading to QuickBooks Online to modify these accounts.

You may check out these article for future reference when you're ready to setup the accounts and users in QuickBooks Online:
Let me know in the comment section if you have other questions. I'd be happy to lend a helping hand. Have a good one.
