I noticed the penalty on the summary page that Turbo Tax prints with your return. At no time did Turbo Tax alert me to a penalty. Or Present any information in Q&A that led me to understand that I needed to do something else. That should have been a no-brainer for Turbo Tax. Ultimately, they failed to live up to their maximum return advertisement. On my own I eliminated a $67 dollar penalty which I didn't deserve.
I found the forms by doing a google search on IN Estimated Tax Penalty. That's where I learned about the form IT-2210 and IT-2210A. My point here is that Turbo Tax did not alert me to the penalty, and thus did not present the IT-2210A form automatically to try to remove the penalty.
To fill out the IT-2210A you have to report your total income and credits at the 3mo 5mo 8mo and year end. It then does proration math to determine if you had underpaid at any point. Everything on the IT-2210A form is automatic. To determine my 3mo total income I took my Gross Income minus my ROTH Conversion and divided by 12. That worked well for me.
