I’m trying to transfer money between accounts and the number that it’s using is no longer associated with my account

I'm pleased to have you here, @chrislawn2. Let me help you transfer money between accounts in QuickBooks Online.

To transfer funds to your vendor, we need to set it up by either entering the vendor's bank account manually or inviting them. This way, you can pay your vendor electronically using a bank transfer. 

To add the vendor's bank account, follow these steps.

1. Log in to your QuickBooks Online account.
2. Navigate to the Pay bills online by selecting the + New button and then Pay Bills Online.
3. To set up a vendor with open bills, click Set up Bank Transfers within the same line as the Payee. 
4. To set up a vendor before there are open bills, click Set up vendors for bank transfers. You'll need the account number for the vendor.
5. Choose Enter vendor's bank account info.
6. Click Next.
7. Input the vendor's bank account information.
8. Select Save.
   
   

Otherwise, you can invite your vendors to your account. For more detailed steps, please see this resource: Set up a bank transfer to a vendor.

Meanwhile, I will attach this article to guide you supplement a vendor bank account in Online Bill Pay: Add a vendor bank account.
