multiple returns

You can file multiple Estate and Trust tax returns using the TurboTax Business Edition.  The Business Edition can only be installed on a Windows based personal computer, not on a Mac or online.  The Business Edition cannot complete a personal tax return, Form 1040.

Go to this TurboTax website for the Business Edition - https://turbotax.intuit.com/small-business-taxes/

You can use the TurboTax online or desktop editions for your personal return.  If you will be entering a Schedule K-1 from the Trust you will have to use either the TurboTax Premier or Self-Employed online editions.  You can use any of the TurboTax desktop editions for the Trust Schedule K-1.

Go to this TurboTax website for the online editions - https://turbotax.intuit.com/personal-taxes/online/

Go to this TurboTax website for the desktop CD/Download editions - https://turbotax.intuit.com/personal-taxes/cd-download/

If you need to file returns for trusts (Form 1041), then you need TurboTax Business.

See https://turbotax.intuit.com/small-business-taxes

Note that TurboTax Business must be installed and run in a Windows environment; there is no online or Mac version.

Also, note that you will need a separate product for your personal return as TurboTax Business does not support preparation of any Form 1040 variant.
