This is a BC return with entries in every one of box 52100 to 52220 except for PEI, YT, NT, NU and Outside Canada.  After 3 calls to Efile Help Desk over 4 days and 3 calls to Profile Support over the same period I paper filed to get on with other work.  Efile Help Desk's comment about CPP retroactive payment was because the difference in CRA's net income and the T2203 total Column 4 (and Profile's net income) equaled the CPP retroactive payment
