Amending 2009 or earlier Corporation returns in TurboTax Business 2010

Although TurboTax Business 2010 includes an option to amend 2009 (or earlier) Corporation returns, we strongly recommend going back to the prior-year TurboTax Business version – if you still have it – and amending your tax return there. (Or, consider purchasing a prior-year TurboTax Business version.)

Otherwise, you'll need to manually enter all information and calculate the taxes and credits yourself.

You can use TurboTax Business 2010 to amend a previously-filed 2010 business return that you didn't prepare in TurboTax. You'll start by re-creating the return in TurboTax, then you'll amend it.

1. Open TurboTax Business 2010.
2. Click the Amend Return button.
3. Now click the amend a 2010 return not prepared using TurboTax link.

   

4. On the next screen, select the type of business return you are amending (LLC, Partnership, Corporation, S Corporation, or Estate/Trust) and click Continue.

   Note: If you're amending a Form 1040 return with a Schedule C, you'll need to use the TurboTax Home & Business or TurboTax Premier instead. More info
