Hello there, @Pablogm13.

Thanks for joining this thread about importing transactions in QuickBooks Desktop. I'm here share some more insights.

When uploading your transactions, you still have the option to review all the transactions. You'll have to check it by yourself and remove the duplicates if necessary.

Depending on the mode you're using, please refer to this article for the steps in removing duplicate transaction.

That should keep you going today, Pablogm13. Let me know if there's anything else you need. I'll be around for you. Wishing you all the best!
