I need to purchase Illinois State turbo tax that can transfer information from my federal and MD state

[IreneS]

If you are using TurboTax Online, you can add another state to your return using these steps:

1. Click State (in the black bar on the left) and then Continue.
2. On the Status of your state returns screen, click the box Add Another State.
3. Choose Illinois on the next screen.
   

Information from the federal and MD returns will flow into the Illinois return.
