After you file

@mjpb52 You would have to manually write that on the signature line or 3rd party designee line on a printed return.  As stated above, there is no way for a personal representative to sign an electronic return - that can only be done on paper.

Suggest that you read IRS Pub 559 (Survivors, Executors, and Administrators) for a lot of good information about filing the final return and estate return and other requirements.
