How do I add additional returns to my TT account for a deceased parent and trust? When I log in to my account, I see no options for adding additional returns.

I will prefer to have all of these returns under one single, existing TT account. Do I need to create new accounts for each entity (decedent and trust)?

Yes if you are using the Online browser version you need to start a new account.  Online is only good for 1 return and 1 account.  

To prepare a 1041 Estate/Trust return you need Turbo Tax Business.

The small business program (TT Business) is for 1120 Corporation, 1120S Corp, 1065 Partnership or 1041 Estate/Trust returns and will not do your personal 1040 return.   It  is a separate program from the Desktop Home & Business program or the Online Premium version.

Turbo Tax Business  is not available to do online or on a Mac.  And you can have both TT Business and TT Home & Business (or any personal version) installed on  your computer at the same time.

You can buy the Window's Business Desktop program here…..
