What will you charge me to file this ammended return?

No one can see your tax return so we would have no idea if you upgraded to a higher edition to complete the amended tax return.

If you followed the procedure to amend a tax return using TurboTax and did not upgrade to a more expensive edition to complete the amended return, then there would be no charge to amend the tax return.
