First, if you have e-filed your taxes once you click the orange 'File my Taxes' button it is the same as if you have printed your taxes and then dropped them into a Post Office mailbox --you cannot get access to it.
Second, since you chose to file early, and the IRS has not started yet to accept tax returns (and will not until 1/28/19) your tax return is stored and inaccessible to anyone until the IRS starts accepting returns.
