How can i remove this

Please show a screenshot that includes the layers panel. Your document is a psd so it may be on a separate layer.

If you mean you want to be able to see the content that used to be there, it's not there anymore and you won't be able to retrieve it. When there is one layer, the new pixels replace the previous pixels.

The is a Remove tool for smaller objects in a scene, but it is unlikely to help with your image.
