DMarkM1,
Thank you so much for staying with me on this. My own calculation was in error due to my misinterpretation of Line 13 instructions which was to include the amount from line 19 of ALL preceding columns not just the preceding column. I have submitted a letter to Indiana DOR for a review of my return where they disallowed the Turbo Tax calculated IT-2210A which showed I owed no underpayment penalty. Thank you again for the effort you have put in to assist me in this matter!
