Duplicates can occur when your bank simultaneously sends information to QuickBooks while you manually upload the same data, Super. Let me elaborate on this further.
QuickBooks is dependent on the data it receives from your bank. Once you connect your account, it automatically import your banking information to the system. However, if you experience synchronization issues and choose to upload entries manually, this will lead to discrepancies like duplicate transactions in your feed.
Moreover, if duplicates appear even if you're not manually uploading entries to the software, I encourage you to review your bank transaction from your bank's website, as well as reaching out with their representative. This way, they can further check and identify the cause of this issue.
To handle these duplicates, you'll have to manually exclude them. Once done, please send the correct transactions to TurboTax. At the same time, if the issue lies within TurboTax, I suggest contacting their support team. They can offer the proper guidance in handling this matter.
In case you're experiencing trouble in transferring information to TurboTax, here's an article you can read for guidance: Quickbooks-Self Employed data won't transfer to TurboTax Self-Employed.
