T_K_ and all!
Thanks for your guidance. I struggled to find Forms and saw subsequent posts stating that you can't access Forms through online TT, but then folks were simply resubmitting and it was being accepted. Voila, got it through. Weirdly, my return still has this non-qual pension income listed in Schedule 1 and not 1040 line 1, as it had been in years past. But obviously it removed the duplicate entry.
