In the confirmation screen, you can see, among other things, what information you have reported.

How to find old confirmation screens:

You can retrieve the confirmation you receive when you have reported information via TastSelv Erhverv at a later time. Select the menu item ‘Forespørgsel på indberetninger' (Enquire about reporting) after you have logged in.

Even though your accountant may have entered the declaration, you can retrieve the confirmation in TastSelv Erhverv.
