I think I have found a significant error in this year's software. My estimated taxes for 2018 paid by the due dates are correctly recorded. The 4 estimated state payments total correctly transferred into my state form, and the 4 estimated federal payments total correctly transferred into my federal form. HOWEVER, the state estimated tax information gets transferred into the federal form by the State & Local Tax Deduction Worksheet which currently does not pick up the 4th and final 2018 payment due 1/15/19. I called Turbotax and spoke with their support person and they sought help from their next level, "TA". I got back an unsatisfactory answer but a workaround to change the 1/15/19 date to 12/31/18 so I could eFile. If I am correct anyone filing estimated taxes that have a state tax deduction to use on their federal return is going to be screwed big time as they will miss deducting their 4th quarter state estimated tax payment.
