How do I flip my bank transactions to show the most recent first - I must have inadvertently clicked something to flip the transactions?

Thanks for posting in the Community, @sara20.

I'd be happy to assist you with flipping your bank transactions so that the most recent transactions appear at the top.

If you’re referring to the bank register, QuickBooks Online offers multiple ways to sort your this, including ascending and descending order. To show the most recent transaction, you can follow the steps below:

1. Select Accounting on the left navigation menu and choose Chart of Accounts. 
2. Click View register for the account that you'd like to view.
3. Select the drop-down arrow next to Date to switch from ascending to descending order, or vice versa. 

I’ve also added an article for additional information on sorting options: Sort A Bank Register In QuickBooks Online.

That’s it. Let me know if there's anything else I can do for you. Thanks for dropping in. keep safe.
