“Charter” referred here is a separate document mentioned in Article 6 of the treaty:

The Union recognises the rights, freedoms and principles set out in the Charter of Fundamental Rights of the European Union of 7 December 2000, as adapted at Strasbourg, on 12 December 2007, which shall have the same legal value as the Treaties.

The provisions of the Charter shall not extend in any way the competences of the Union as defined in the Treaties.

So the Charter is about human rights, and as the treaty makes clear, doesn’t extend the competences of the Union. Poland and UK wanted to put a further point on this for some reason. It is not a carve-out from the treaty.
