Credit note entered correctly or incorrectly?

Hello, can someone tell me if I entered everything correctly?

I sent an invoice to my customer via Peppol (for the first time). They asked for a few edits to be made to the invoice, recommending that I should not delete the invoice (as it had already been sent), but instead add a credit note for this invoice (which was also sent to the customer) and then issue a new and correct invoice. Invoice 1 was therefore credited (with a credit note linked to invoice 1) and invoice 2 was then sent and paid by the customer. My dashboard states my income as the correct amount (and therefore not double).

Now I want to do my tax return and I see a double amount in my quarter summary. It also states that a credit note was issued and the final amount is correct and is not counted twice.

I assume I have done everything correctly, but would like to double-check. Is this the correct way to proceed?
