There is the tension in the string.

There is also an equal and opposite reaction at the wall.

If the string is under tension, there must be a reaction.

The reaction is equal and opposite to the tension, so depending on the angle of the string, the reaction will have a component normal to (and into the wall), and parallel to the wall. The sum of those two components, as vectors, is equal and opposite to the tension in the string.
