Hello, @martina1.

E1 is for the total value of goods sent to customers in other EU countries. While E2 is for the value of goods you've received from your suppliers in other EU countries. Let's make sure to enter your supplier and customers' billing address.

Also, you can run the VAT detail report to view the transactions included in your VAT3 report.

Lastly, I'd recommend consulting with your accountant. This way, you'd be guided in reviewing the taxability status of your transactions.

Stay in touch with us here if you have other questions about managing your VAT. I'm always here to help.
