In order to fill out additional forms after you have filed TurboTax requires one to do so as if you were amending your return. Nevertheless it is not necessary to send the 1040X to the IRS.
At the moment the IRS has not provided a time-table for the turnaround on requests made for these forms. It is a common issue this year as many people filed their returns before receiving 1095-A. It can be difficult and time consuming to contact the IRS over the phone but that would be the best way to receive the status of your return.
