My NetFile attempt did NOT complete as I was outside the CRA hours of operation.  I then noticed my T4RSP information was not there, so want to add it before trying the NetFile again.  However when I access the return it goes back to the page "Next Step to file your return" with no option to go back to the return itself and edit/review?  I'm stuck.  Question is, how can I go back to my Return so I can continue to enter information?
