Put off getting something done about amateur (7)
I believe the answer is:
delayed
'put off' is the definition.
(I've seen this in another clue)
'something done about amateur' is the wordplay.
'something done' becomes 'deed' (I've seen this before).
'about' indicates putting letters inside.
'amateur' becomes 'lay' (similar in meaning).
'deed' enclosing 'lay' is 'DELAYED'.
'getting' is the link.
(Other definitions for delayed that I've seen before include "Made late" , "Put back" , "Shelved" , "Hindered" , "Held up, back" .)
