I am not able to amend my return on TT 2017. When I open the file it says I need form 8606-T, which is now ready. Because of this I never see the welcome page to amend.

I am aware that to amend a return you choose the option at the bottom left from the Welcome page.   When I open my return the first page shows the alert that form 8606-T, which I was waiting on, is now ready.   I have already filed and received my refund.   Now I need to amend but I am not able to find the option.
