Without more context that makes no sense. Perhaps the DTP (what does that stand for?) was referring to a paragraph style, perhaps called something like "R Headline". Your question about a template makes no sense.
Another possibility is that only some pages have a headline and for only those pages you should use Headline R as the Master page. Scour the Pages panel and the Paragraph Styles panels for clues. You could also compress the file as a .zip file and put it online somewhere then paste a link in a reply so others can examine the file. If you do that be sure to remove any sensitive or confidential data and sae a copy.
The easiest way to put such a file online is to throw it into your Dropbox/Public folder then right-click on it and Copy Public Link. If you don’t have Dropbox (shame on you), get it here.
