TurboTax Online is no longer available for 2016 tax returns as we're moving in to Tax Year 2017.
You will need to download the amended software from the Tax Home - "Your Tax Return & Documents" Section. You can select which tax year you want to amend and download tax file for Windows users. (Please view attached image)
If you have a MAC computer, you will need to request the "MAC Amend software" using the following link:
Once TurboTax confirms your purchase, they will send you an email with a download link for the MAC amend software.
