When I e-filed again, following the guidance of other successful folks, the return did not include 2210. It was accepted. Like BobbyO, I do not see the need to include 2210, as I paid my entire 2018 estimated tax obligation by applying it from my 2017 refund. Thus, the Feds received all of their tax payment from me upfront, and as it turns out, I an entitled to a significant refund for 2018. There was no underpayment. I have never before needed to attach 2210. If after the 'official' fix comes out, I determine some unforseen need to include the 2210 just for the record, I can either amend the return or IRS will come a calling. In either event, no money is owed and no penalty is due. This whole mess has been frustrating beyond words. And for me, it's been going on for more than three weeks.
