Restore my homepage contributions display

I accidentally deleted a forked repo. As a result, many small green boxes in the contributions display on the homepage disappeared. Now my project director wants to see my activity on Github based on the number of my contributions. How can you find my green boxes? I tried to restore the 90-day deleted repo in the setting, but because it is a fork of the warehouse, it cannot be restored. I now hope to contact customer service to restore my green boxes.
