Paper bill in America - cover includes nothing! (7)
I believe the answer is:
tabloid
'paper' is the definition.
(tabloid is a kind of paper)
'bill in america cover includes nothing' is the wordplay.
'bill in america' becomes 'tab' (american english for the bill at end of meal say).
'cover' becomes 'lid' (lid is a kind of cover**).
'includes' is an insertion indicator.
'nothing' becomes 'o' (looks like zero - 0).
'lid' going around 'o' is 'loid'.
'tab'+'loid'='TABLOID'
(Other definitions for tabloid that I've seen before include "Newspaper with half-size pages" , "Type of newspaper" , "Populist newspaper" , "Newspaper with smaller pages and popular content" , "Smaller-sized newspaper" .)
