In disagreement when accepting Fleet Street offer? (2,4)

I believe the answer is:
at odds
'in disagreement' is the definition.
(I've seen this in another clue)
'when accepting fleet street offer?' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'accepting' indicates putting letters inside (inserted letters are accepted).
'fleet street offer?' becomes 'todd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'as' enclosing 'todd' is 'AT ODDS'.
Can you help me to learn more?
(Other definitions for at odds that I've seen before include "In disagreement or conflict - like bookies?" , "Not in agreement" , "In disagreement or dispute" , "Disagreeing" , "In opposition or disagreement" .)
