If you are in TurboTax CD/Download EasyStep Mode, scroll
to the bottom of the Detailed Tax Summary and click on the link for the year
over year comparison.
If you are in TurboTax CD/Download Forms Mode, on
the DSUM - Detailed Tax Summary page you can toggle between 2017 and your
spouse (if you have one) by clicking on one of the boxes on top of the second
column.
If your info didn’t transfer properly, start a new
return and try the transfer again. Make sure the 2017 file you are using is
