Thanks for checking in with us, caspernjoy11-gma.
If you are referring to the payment method posted in QuickBooks Online (QBO), it will show you only the last four-digit and the expiration date. Even the Intuit representative can't view the full details of the bank information. For online banking, you'll see the bank name and the Chart of Accounts (COA) information only.
If you want to edit the bank information in the COA, you'll only see the name of the financial institution and the Number (if you enter them on the Account page). Just in case you recently changed the bank details on your financial institution for an account you connected on your online account, just update your bank account sign-in information in QBO.
Feel free to visit our Banking page for more insights about managing your bank feeds and reconciling accounts.
I'm just one post away if you need a hand with updating your business information or any QBO related. Just add the details to your reply and I'll be there to address them for you. You have a good one.
