It depends on where you did the formatting. There are several ways. Try 
not to edit files which are in the extension directory.

heres my approach:

copy template file from /tt_news/pi/???

to a path within the fileadmin like
fileadmin/template/tt_news.html

Then put into Typoscript:

plugin.tt_news {
   templateFile = fileadmin/template/tt_news.html
}
