Are you saying that 2017 Turbotax will calculate 2018 estimated taxes using 2018 rates? If so, if my income situation will change significantly in 2018, e.g., retirement in 2017, how do I calculate estimated taxes for 2018? Should I create a new test tax return on 2017 Turbotax using my projected 2018 income (social security, rental income, and 401K distributions) and then cause Turbotax to calculate estimated taxes for the (next) year?
