Thank you for posting your concern here in the Community, @cammccaa.
Let me walk you through on how to hide the bank account from your Dashboard.
You can inactivate it by selecting the Delete option in the register. This way, this bank account won't show up on your Dashboard anymore.
Here’s how:
1. Click on the Gear icon, then Chart of Accounts.
2. Find the old bank account you want to delete.
3. Go to the Action column, then choose Delete from the drop-down.
4. Select Yes to confirm the action.
For more details, you can read through this article: How to Delete an Account and Restore It.
Feel free to comment below if you have other concerns. I’ll be very glad to help you out. Have a good day!
