After two rejections, I finally got my efile to go through successfully. Others have tried steps that I outlined elsewhere and were unsuccessful. In thinking about why that might be, I remembered that I manually downloaded the Turbo Tax program updates (based on a Forum suggestion) even though the "UPDATE" option on program downloaded from the disk suggested repeatedly that my program was "up to date" I had Box A checked and "85% waiver" recorded (by TT) but had two rejections. After downloading the manual update, I clicked on the "Explain" button below and to the right of BOX C on Form 2210, Page 1. It took me to the "WaiverExplanationStatement" form that each of the rejection email notices said needed to be completed, I wrote in a simple explanation (in my case, that withholding and est. tax payments exceeded taxes due) and closed the form, resubmitted the efile, and it went through successfully. After the fact, I then opened the Form 2210 on my return, and found that both the Explanation Statement and a "85% waiver exception" worksheet had been autogenerated (and presumably filed with my return).
