Process I used to modify the return:
I searched under topics for 'Underpayment Penalty' and followed the interview questions which removed the penalty. I have returned to this, and I cannot (as far as I can see) get the penalty to re-appear as it was on the return I filed.
Use online TT:
I do not use the online application. I use Premier on a Mac, OS10.14.6

When I try to file an amended return, TT does not recognize the the amended return is different from the one I filed originally. It tells me that I am not due any additional refund.
So...thanks for your reply, but no resolution so far.
