While we understand how frustrating this is, at this late date it would be difficult to determine what went wrong when you did your Auto-Fill. It might be that that the slip wasn’t available yet, or that TurboTax thought it was a duplicate and didn’t download it, or maybe there was a connection issue.
While we try to ensure that Auto-Fill imports all the information correctly, as per the CRA Terms and Conditions of Use, you are required to ensure that all applicable fields contained on the tax return that you will file with the CRA are completed, and that the information provided is true and accurate.
