I've only used online version, never cd or download. The instructions you outlined are consistent with the instructions turbo tax provided and i followed them exactly. When I click "amend return", i get a blank screen. As i mentioned, i have tried it on multiple separate PCs and browsers on different networks and get the same result. You can see in the web address the "error".
