You would need to buy Turbo Tax Business program to prepare a 1041 return. Business is only available for Windows Desktop computers. You can buy 2019 here. Pick Business on the far right side.
Do you need to file a final personal return ? If so you need to file a 1040 not a 1041.
The 1041 is only if the estate had income they need to report after the date of death.
If the estate has significant assets, you need to file a Form 1041 for the estate, and you have absolutely no experience in such matters, you should seriously consider having the 1041 professionally prepared.
Before you decide to do it yourself I suggest you read this IRS publication.
IRS Pub 559 (Survivors, Executors, and Administrators) for a lot of good information about filing the final return and estate return and other requirements.
