Did you and your brother use the same account and user ID for your returns last year? If you did, then the second return overwrote the first one and it is lost forever. With online TurboTax you get one return per fee.
Try looking to see if you have another account or user ID for yourself.
Many people have multiple TT accounts and forget how to access them. Log out of the account you are in now.
