I decided not to create a $1 interest income entry.
I learned from Intuit support that I need to check the efile boxes in the Profile for both the form 1040 and the form 114; even though the 1040 will be paper-filed. This worked. In the e-file screen, only the form 114 shows as available to be efiled. Intuit should have a diagnostic to that effect. Thanks to all for you comments.
