It can be challenging when you can't find the imported transactions, aoypossible-gmai. Not to worry, I'm here to help you locate them in QuickBooks Online (QBO).

When you upload bank data, the transactions will be imported based on the date indicated in the file. It could be the reason you can't view them in the For Review tab. To fix this, I recommend sorting the dates. Doing so helps you modify the list of transactions from oldest to the latest. I'll show you how:

1. Go to the Transactions menu and then select Transactions.
2. Choose the bank account you've imported the data.
3. Click the Date drop-down arrow to sort the date.
4. Once done, you'll be successfully viewing the newest transactions.
   

In addition, make sure the Page Size is set to 300. This way, you'll be able to view them all. You can do this by clicking the Gear icon on the For review page. Then, scroll down to the bottom to make some changes. For visual reference, I've added a screenshot below.

Please keep me posted in the comments if you need additional assistance managing your transactions in QBO. I'll gladly help. Take care.
