why do you send me an email stating I have two accounts if you won't let me combine them to get past data

Please see the following TurboTax answer for additional information on combining two  accounts:https://ttlc.intuit.com/replies/5304347

Will the downloaded account data update the current account data for subsequent years?  I now have three different Turbotax accounts for 2014, 2015 & 2016.
