No. You may not e file a return that was not originally filed through TurboTax Online.
You are able to upload a pdf from other tax preparers directly into TurboTax Desktop version. There are limitations to the transfer, such as depreciation. It is best practice to review the upload carefully and make any adjustments necessary.
Here is the link with the instructions.
