I need auto press enter when my script write text.

TEXT PLACE:  https://gyazo.com/a8cd0ad5100fa0bb2d9f7865e8192128

TEXT SCRIPT[CHROME]:  https://gyazo.com/6588261f4928bd1b35a7000fb9199ba0

My script: 

pQ += $ ( ".amount" ). html ();

and

$ ( 'TEXTAREA' ). val ( pQ );

When i paste my scritp in chrome console i get this:

When i try add this:

var e = jQuery.Event("keypress");
e.which = 13; //choose the one you want
e.keyCode = 13;

and 

$('TEXTAREA').val(pQ); $("TEXTAREA").trigger(e);

When i trys this auto press enter don't work just script paste text in TEXT PLACE
