In certain months, transfers appear twice. One as a deposit and one as a payment. I've tried entering it in the register but it does the same thing.

Hello @victorymachining,

In QuickBooks Online, all data of your downloaded transaction is based on the information provided by your bank. With this, I'd recommend contacting their Technical Support so a specialist can update the mapping accounts of your transaction to stop it from creating a duplicate copy.

In the meantime, you can exclude the other copy of your transfer transactions. Let me show you how.

1. Go to Transactions.
2. Select Banking.
3. Choose your bank account.
4. Under For Review, select all transactions in question.
5. Click Exclude.

In addition, here's an article you can read to learn more about excluding your bank transactions: Exclude expenses from downloaded bank transactions.

Once done, you can go ahead and delete your transactions from the Excluded tab. To do so, select all your excluded transactions and click Delete.

Lastly, I've also included this helpful article for the steps in case you need to start balancing your account register: How to reconcile your accounts so they always match your bank and credit card statements?

I'd suggest getting back to this thread if you need assistance with your transactions. I'm always here to back you up. Take care and stay safe!
