I created a dependent's tax return for the first time. I grabbed what I thought was the SIN from one of the Tslips, however I grabbed the incorrect number. I didn't know it was incorrect until I tried to Netfile and got an error and was told to double check the information. I have edited the SIN many times and it won't save. TurboTax has already deducted this return from my available returns and I hope I don't have to start from scratch and use another one of my available returns for the same person.
Is there a way that I can change the SIN after the data has been certified?
