I try to run the automatic entries for the VAT Return but get this error message:

You cannot use this account (7380 Telefon- und Internetkosten) in this journal, check the field 'Allowed Journals' on the related account.

This kind of makes sense as 7380 is a normal expense account and shouldn't be involved in the entries for the VAT return. But I don't know where this comes from? Any idea where to check would be appreciated.

I run Odoo15.0+e.
