After you file

And in answer to the question about purchasing another CD/download to get more e-files---no, you would not be able to do that even if you had not already mailed the return.    The limit of 5 federal e-files is an IRS limit---not a TurboTax limit--so purchasing another CD/download would not allow you to e-file any more returns.    Once you reach the limit of five, the only way to file additional returns is by mail.
