Makes corrections and finishes after turning me over (6)
I believe the answer is:
emends
'makes corrections' is the definition.
(I've seen this before)
'finishes after turning me over' is the wordplay.
'finishes' becomes 'ends' ('end' can be a synonym of 'finish').
'after turning' says the letters should be written backwards.
'over' says to put letters next to each other.
'me' in reverse letter order is 'em'.
'ends' after 'em' is 'EMENDS'.
'and' is the link.
(Other definitions for emends that I've seen before include "Makes improvements or corrections" , "Send me (anag.); corrects" , "Corrects and improves the text" , "Improves,corrects" , "'Corrects, puts right (6)'" .)
