Put off being fed up with having made a mistake (8)
I believe the answer is:
deferred
'put off' is the definition.
(I've seen this before)
'fed up with having made a mistake' is the wordplay.
I cannot quite see how this works, but
an anagram of 'fed' is 'def' which is located in the answer.
'mistake' could be 'erred' (I've seen this before) and 'erred' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'being' is the link.
Can you help me to learn more?
(Other definitions for deferred that I've seen before include "Put off to a later time" , "Postponed" , "Put back" .)
