More cut up about Turkey (5)
I believe the answer is:
extra
'more' is the definition.
(I've seen this in other clues)
'cut up about turkey' is the wordplay.
'cut' becomes 'axe' (both can mean to cancel or remove).
'up' says the letters should be written backwards (in down clue: letters go upwards).
'about' indicates putting letters inside.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'axe' in reverse letter order is 'exa'.
'exa' enclosing 'tr' is 'EXTRA'.
(Other definitions for extra that I've seen before include "more than is necessary" , "One in crowd scene" , "on top" , "comes to 16 [TEST MATCH]" , "23 player?" .)
