What to do when no option to amend return on desktop?

I netfiled returns for my wife and I, and now need to amend them. This is on the desktop product. Unfortunately, for reasons I can't explain, TurboTax has "forgotten" that I already netfiled my wife's return so doesn't give the "Change Return" option there. (It's there on mine.)

 

How can I convince TurboTax that I want to amend my wife's return, not submit it for the first time?
