@KCN It is frustrating. I've got a case where because the O/P is not included in line 11 a), TT calculates an underpayment for the first two quarters. But then it doesn't follow through and calculate the penalty, Line 19 shows zero. I could simply e-file as is, because that's the result I want (zero penalty), but I'm wary that IRS might automatically flag and reject it, in that first 24 hours when you receive that cheerful TT email "Good news, your tax return has been accepted" instead it will be bad news. Then what do I do, try the work-arounds?
Worse comes to worse, I will just mail the return with the Form 2210 problem fields whited out and corrected. Should be only line 11a) and 12-16. I don't owe any taxes and am applying all of my 2021 overpayment to 2022. Hopefully, the problem will be fixed for next year.
