I use TurboTax Home & Business for myself. I also file my son's taxes. While he has lived for the most of 2019 in the same state as myself (ME), this year he has also earned some very small salaried income in 2 other states (OK and CA). How do I file his information of these two earnings in two additional states? Do I do that from within the TurboTax Home & Business? Nome much does this additional state software cost?
