Okay well you need to file a corrected police report (amended they are also called) giving your side of the story.  Detail will make a difference here.  Details such as if there is a turning lane: if the turning lane has its own signal - those type of details.  Because honestly the liability for you either way and with either story is not great with out those details.  You made a left hand turn in front of on coming traffic and across the other car's lane of traffic.  I think that in most states that would be bad liability for you.  Perhaps you should speak with an attorney in the area on the matter.  Good luck.
