Please help me fix my WordPress theme upload issue on Envato Mart

HELLO . I have a problem in uploading my template to Envato Market
i don’t know where to find this file (style.css) . I searched in the file manager and found files similar to the name (style.css) which I uploaded, but to no avail.

I am trying to submit the item for sale
