Am told I am not eligible to Netfile my Qc return. CRA went through no prodblem. How do I identify the problem?

What is the exact error message that you are getting?

Error Message preventing me from transmitting netfile qc : "A business form is opened TP-80 but there is no business income on lines 120 or 146 or are negative...  

But I was able to send my fed returns and the income data is identical!

I really really would prefer NOT TO HAVE TO MAIL THEM. Help!

@Richardsgareau Please try closing the T2125 first. In Forms mode, go to the T2125, select Edit>Forms>Clear Current Form, and then Edit>Forms>Close Unused Forms. Then repeat for the TP-80, and Schedule L.
