Estimated Tax Module Bug?

[wafer1]

When I use the estimated tax module in TT2019 Premier and adjust income and deductions, entering the same amount as 2019 in every category, at the end it says income is zero.  Seems like a bug and makes me skeptical of the calculations for estimated tax payments or W4 adjustments.

Yep, I'm seeing the same thing in TT2019 Deluxe.  Also, the estimated 2020 tax liability at the end seems to be unaffected by the amount I enter for 2020 in the "Adjustments to Income" page, making me even more doubtful about the accuracy of the calculations.

Looking forward to clarification or a software patch!
