Is there a version of TurboTax to use to Netfile my return plus Netfile for two grandchildren, or do they have to file using a different TurboTax program?

Yes, if you have Windows installed, you can use the desktop version of TurboTax.

Alternatively, you and your grandchildren can use TurboTax Online.

Thank you for choosing TurboTax.

Thanks. I received a telephone call from TurboTax and was advised I needed the Standard desktop version to  NETFILE more than one return so this is my understanding at the moment.
