This wasn't originally my question, but I've got a horse in this race too (ie a similar question submitted). You said "DO NOT include any estimated tax you paid for tax year 2016 but you paid after Dec. 31, 2016." I think I understand your logic, but the TT program, within the link regarding What Does This Include?, specifically says, "Estimated tax payments for 2016. Add any paid in 2017 for 2016 (it's common for the forth quarterly payment to be made in January)". Does this portion of the TT program need to be revised?
