I have the same issue.

I entered my date of entry, and answered the question of: are you a Canadian citizen as no, and I answered the question of are you a permanent resident as yes. Not sure what else to do to indicate that I am an immigrant!!

Need a refund or resolve this issue. Such a waste of time. Even your paid tax expert couldn't resolve it and my time and money was wasted on that too.

It asks you to enter your income from before you were a resident of Canada. This is where the error is. Have you entered your foreign income?
