I imported the bank information. Months i have reconciled, now all the transactions are showing again, to add or match. If i add, wont that double the transactions?

Thank you for the details, userilsa.

Uploading transactions from your bank into QuickBooks Online is one of the ways to record them. Let me guide you on how to exclude transactions to avoid duplicates. 

Here's how: 

1. Go to Transactions on menu ☰.
2. Select Banking.
3. Click on For review tab.
4. Put a checkmark ☑ on transactions you already added.
5. Click on Exclude.
   

If you accidentally exclude transactions, you can click the Excluded tab and select Undo.

Once your done adding new transactions, you can also start reconciling an account inside QuickBooks Online. This will help make sure that your accounts are accurate.
