I want purchase max

You can add MAX any time before you file your return but not after you file your return. 

Here's how to get MAX benefits before filing:

1. Open your return and select Review in the left-hand menu.
2. Continue through the various screens until you get to the below screen, and select Add MAX benefits. MAX is only available in TurboTax before you file.
