Delete image on top single post

Hello,

i use this teme for my website (i love this template!) but i like to change some style.

In every post (for example https://www.zenzeroincucina.it/risotto-radicchio-e-arancia/), on top, you have the featured image, the tile of post and then the information (category, date etc).

I want delet the image on left of title but i don’t know how. I try to search on single.php but i can’t finde any reference to the featured image.

Can yo help me please?

Thank’s much
