A warm welcome to the Community, @jamesonson5th-ya. I'd be happy to help share some information about adding another company to the same QuickBooks Online account.
I can see the convenience of having multiple accounts under one QuickBooks account. However, one company file is equivalent to one subscription. That’s why you’ll need to sign-up for a new QBO account to create another company.
If you want to use your existing Intuit ID, log into your current company when creating a new account. Simply click on the Add another company button when creating another account. From there, you'll only be asked for an Email address and Password (you should be using the same email address).
You can utilize the Location feature in QBO Plus and Advanced to manage multi businesses. Otherwise, you should signup for a new QBO account and you can use the same email address to manage them.
