I realised today that I filed my 2010/09 EMP201 last month, instead of the 2010/08 one...whoops. So the 2010/09 submission has all of 08's information and the 08 submission is still outstanding.

Any thoughts/suggestions on the best course of action?

I was thinking to just file 2010/08 with 09's information - it will all recon at the end of the year.
