From Intuit's website: Every year, tax laws and forms change, and in turn, we completely revise TurboTax to comply with the current federal and state requirements. Because TurboTax is designed for a specific tax year, you need TurboTax 2008 to do your 2008 tax return. You cannot convert or upgrade TurboTax 2007 to TurboTax 2008. Answer: Upgrade to TurboTax Deluxe

How to upgrade from TurboTax Basic to Deluxe: At the top of the TurboTax screen select the Federal Taxes tab and then select Deductions and Credits.

Select Guide Me Through and answer Yes on the Any Home Mortgage Payments? screen.

Follow the on-screen instructions for either purchasing online or by phone.
