I didn't have an attachment with last year's return.  I even deleted all my input for current year. it still showed up.  So, I finally just deleted my current year return, transferred from last year and updated the extension request stuff. Still there.  I think I am going to attach the Form 1116 Sch B (i would need to anyways based on earlier returns), and hope that makes the software happy. Just don't want to trigger some hidden desire of the software for the dreaded Form 8453
