Hi there,

I'm not sure if data conversion would cause this, but since the 1040X screen is blank, I'd go to the "Profile" tab along the top of a return and make sure the box for e-filing the Federal Amended isn't checked.

One more thought:

If Miscellaneous Forms  is bold, then look to see if Amended Retun (1040-X) Update  is bold, then go to the next bot item and then look to see if any of tabs are bold. I see an entry in Explanation of Changes tab that I have no recall of where it came from. Possibly the conversion threw something into one of those tab entries.
