I’m delighted to have you here in the Community, @GPF Kanata.
You’re right that QuickBooks 2019 has been discontinued and that said you’re unable to use its online services. Here’s an article for your reference about product discontinuation: QuickBooks Desktop service discontinuation policy
Since you mentioned that you had upgraded to QuickBooks 2021, we can go ahead and use bank feeds for your online bank account. Please follow the steps below to edit your bank account so you enable it for bank feeds:
- Go to Lists.
- Select Chart of Accounts.
- Find your bank account which is already set to use bank feeds.
- Under Account, select Edit Account.
- On the Bank Feeds Settings tab, select Activate Online Services.
- Select any method of connection.
- Click Save & Close.
I also added this article for your reference about how you can connect your bank account for bank feeds: Set up bank accounts for Bank Feeds in QuickBooks Desktop
Regarding with the Account Customer ID, it’s a unique credential used to log in to your financial institution account. With that, you can directly reach out to your bank institution.
Let me know if you need further assistance with your bank feeds. I’m just one post away from assisting you. Stay safe!
