The support has been terrible at best . I needed help reconciling my QBO account and wasted 4.5 hours of my time and talked and screen shared with 4 representatives

We don't want you to have this kind of experience. Allow me to lend a hand in reconciling your account.

Firstly, there are two possible reasons why you're having duplicate transactions.

The first one is if you've connected your bank account to QuickBooks Online (QBO), and instead of Matching the transaction you've manually entered in QBO and the transaction from your bank account, you've only clicked Add.

With this, we'll have to undo those added transactions and match them:

1. Navigate to Transactions, then choose Bank Transactions.
2. Click the Categorized beside the For Review.
3. Locate those duplicate transactions, then click Undo.
4. You can also click the Box of the duplicate transactions beside the date, then click Undo.
5. Once done, go to the For Review tab and Match the transactions.

The second one is that you didn't connect your bank account. However, you've double-entered your transactions. In such cases, I recommend running a Transaction List report to locate the transactions you've entered twice. Once you've found them, open the duplicate transaction by clicking it and then delete it.

After following the steps above based on the situation you've experienced, we can now Reconcile your account so they always match your Bank Statements. For further information and detailed guidance, please refer to this article: Reconcile an account in QBO.

If your account doesn't match your bank statements at the end of your reconciliation, you can check out this article to learn how to fix it: Fix issues at the end of a reconciliation in QBO.
