Arduino's keyboard library uses the US layout. So if you send double quote which in your keyboard layout is shift + 2 this results in a @ which would be the output of the US layout.

I don't know which layout you're using so I cannot tell you what character to send instead.

Alternatively use keyboard.write("\"");
