Retirement tax questions

No. Sorry you still do not understand my question. First, Turbotax has only an entry for the values of end of 2017, not 2016. (You should check the Turbotax program).  Second,  the value for end of 2016 is different than that for end of 2015.  The basis is the same but the values are different, which will affect the percetage of the taxible income.  And Turbotax has given only one entry for the values of end of 2017. One may use that entry for the value of end of 2016 but how about 2015?  I don't think Turbotax is designed for people who reach 70.5 and take their 2 year RMDs in one year.
