Hello exit408cs,
Yes, we've received reports regarding the duplicate transactions from Etsy. This is already investigated by our engineers. I'd also recommend reaching out to our Customer Care Team. They can add you to the list of affected users and keep you updated about the issue. The way to reach them depends on the device you're using. You can use this link for reference: Contact QuickBooks Self-Employed Support.
For now, you can manually remove the duplicates by deleting them one at a time.
We appreciate your patience as we work for a fix.
