How do I get the calculation of an estimated tax payment penalty to be based on the 2016 tax and not the 2017 tax? I am using the forms to input data.

2017 estimated tax payments were greater than 100% of 2016 tax. Therefore there should be no penalty. I need to enter the 2016 tax in the calculation for underpayment.

You would go through the Penalty for Underpayment of Estimated tax interview under Other tax Situations in the Federal program.  You can enter the 2016 data there.
