Are you wanting to prepare a second return for a different person? In Online TurboTax you can only prepare 1 Federal return per account. Another online Federal return would require a second account. Do NOT try to prepare a second return in the same account, or it will overwrite your current return and make it unrecoverable.
For future reference, desktop software can prepare multiple Federal returns with up to 5 free Federal efiles.
Also see my next comment below in case you are asking about a different interpretation of your question.
