I have duplicate bank transactions and I can't exclude one of them since they both say they are apart of another transaction. What do I need to do?

I'm here to ensure that you'll be able to exclude your duplicate transactions in QuickBooks Online, @GFWS.

Being unable to exclude one of the duplicate bank transactions in QuickBooks Online can be caused by a partially matched entry. To get this issue sorted out, I recommend unmatching the transaction from the entry that you have in QBO.

To do that:

1. Go to the Banking menu.
2. Refer to the Banking tab.
3. Select tile for the bank or credit card account you downloaded the transaction from.
4. Select the Categorized tab.
5. Find the transaction you want to unmatch.
6. Select the blue transaction link in the Added or Matched column to see the matched transaction.
7. Press the Undo from the Action column. 

For additional information about unmatching bank transactions in QBO, please check out this link: Learn how to undo or unmatch transactions downloaded into QuickBooks Online.

Once done, you can proceed with excluding the bank entries. 

Here's how:

1. Go to Banking menu on the left panel.
2. Choose Banking tab.
3. Check the box for beside the transactions you want to exclude.
4. Click the Batch actions drop-down and choose Exclude Selected.
