After submitting my filing electronically, TurboTax (desktop) informed me a few screens later that I need to mail in form 8543 with the reason that I selected to not include my 8949 forms electronically. I do not select to not include them, so something is broken here.
Of note I could imagine others will not look past the initial notification that my information has been sent off and stop using the app, missing this critical step (if really needed).
If these forms are needed and TurboTax already has them completed for me, then they should also be printed with the 8543, not just 8543. Another opportunity for someone to not complete this step correctly.
