I also have this issue, CRA code 84, #561. CRA won't accept netfile. It's an issue regarding schedule 11 Line 59140 must equal lines 32000 minus 45350 for Canada training credits plus 32001. The thing is once I subtract 45350 from 32000, it does equal 59140. I've double checked my Canada training credit amount as well and this is correct. Everything checks out. Has anyone found a solution to this? maybe I will mail it in.
