Shockingly I just got the email notice that my efile was accepted by the IRS. That was done with TT online. I had a slight refund due but had Form 2210 filled out because I make variable estimated payments. Box A and Box C were checked, and there was an explanation line automatically attached to my form stating:
Form 2210: Underpayment of Estimated Tax
Part II Explanation Statement
Waiver of Penalty
85% Waiver
