No. When you use online TurboTax you get one return per fee. Each return needs its own account and its own user ID. If you use the same account and user ID for another return you will overwrite the first one and lose it forever. If you try to use that same account and user ID for yourself, your GF's return will be lost. You will need a different account and user ID for yourself now.
