The majority of my transactions have been duplicated with no tab showing to get rid of them. Along with the car/van expenses being disallowable even though mileage tracking is not active I’m on the verge of going with an alternative accounting packag

Thanks for visiting our forum, @Barneyhound.

Allow me to point you in the right direction of deleting these duplicated transactions to your QuickBooks Self-Employed (QBSE) account.

If these are bank transactions, you can exclude them. I'll guide you how:

1. Go to the Transactions tab. 

2. Put a check in each box on the right-hand side of all the transactions you need to be deleted. 

3. Choose the Exclude button in the dark gray bar. 

4. Hit Apply when ready.

For additional reference about handling duplicate transactions in QBSE, read this article: Handle duplicate transactions in QuickBooks Self-Employed.

However, if you are still unable to see the tab to exclude them, you can perform some basic troubleshooting steps to resolve the issue. First, open QuickBooks using a private window. Sometimes, the regular browser tends to hold onto information, and over time it could cause problems while working with QuickBooks.

To save you time, use either of these keyboard shortcuts:

• Mozilla Firefox: press Ctrl + Shift + P

• Internet Explorer: press Ctrl + Shift + P

• Safari: press Command + Shift +N

If that works fine from there, go back to your original browser and clear its cache to start fresh. Also, using other supported browsers can help us narrow the cause of this behavior.

Additionally, I've added this link about adding transactions in QBSE: Manually add transactions in QuickBooks Self-Employed.

Kindly update me on what you find after doing this. I'll be right here if you need anything else. Have a great rest of the day!
