I find it most helpful to think of edges in terms of North and South (top and bottom pair) and East and West (side to side pair) it is then easier to fill in the information as to which direction my edgeflow is going and which way do I want it to flow…
then you employ the already stated techniques of how to change the flow…
one last item might be to take control of edge flow by removing a face or faces that need to be rearranged, that would be accomplished by selecting the face/s then “x/delete face”… (I find it easier to see what needs done with a clearer designation of the problem) then when edges are sorted out it’s easy to put faces back in
