Thanks for updating me. I called CRA and they said there were many options for doing my corporation income tax that did have electronic submissions. Unfortunately not TurboTax. Since the code is available in the personal tax software and since CRA supports it, I remain surprised the TurboTax is not supporting this for T2 submission. I have mailed my form but with the current mail situation have no faith whatsoever that it will arrive and be processed. Hopefully this will get on Turbo Tax's enhancement list before next tax year.
