After you file

thanks so much.  This is what I was looking for.  

I went to my T4A summary and the amount CRA says wasn't entered is listed:

but I can then not find it anywhere else.   my total income doesn't include it and it is the amount the CRA says is missing and saying I now owe plus interest.    I do see a T4a Taxable patronage allocation. i have no idea what that is, which is a bit less than 20% of the amount I added in the T4A box above.    Any ideas?
