I just filed my daughter taxes, how do I file mine now

The same way. However, when using the online version you can only complete and file one tax return per account. You can create a maximum of 5 accounts per e-mail address. So log out of the account you're using right now. Then click the "create account" link under the password entry field and go from there.

Do note that you can not import from one account to another. It's not possible. So you will be doing your tax return from scratch with no possible way to import anything from last year's tax return.
