I am receiving these codes when I am submitting my return. I have all my tax-exempt income entered as I worked on a reserve. It talks about filling out a T90 form but it is filled out. All it consists of is my tax-exempt employment income. My T4 has a box71 which seems like I have to enter it. (Seen discussions where you don't enter it) If I don't enter it I get an error on my t4 to fix.
Exact same problem. I even tried the free H&R Block online version. Same error code. Tried again this morning. Thinking TurboTax update may have a fix. No. Now my account is locked. I've been using Turbotax for years to netfile. Now I have to use snail mail. :( Trying to speak to a human on Turbotax to tell them is ridiculous. Why did Government even need this new T90 form? To make things even more difficult for us? Does Turbotax even monitor these discussions? Hopefully someone fixes this issue. Seems to be on both sides. CRA and tax software providers. Just so disappointed. :(
