In TurboTax Online, you can just print the page using your browser’s print feature. Usually you can just press CTRL+P (Command-P on Mac) and the print dialog will appear.
In TurboTax CD/Download, the easiest way to print the year over year comparison is to go into Forms mode. Do this by clicking on the “Forms” icon on the top right. Then click the “Forms” button, which has now moved to the left. Search for “DSUM”, select it from the list, then click the “OK” button. Make sure 2016 has the X in the box. Then select “Print Form” under “Print” from the “File” menu on the top left. Select “DSUM” from the list, then click the “OK” button. You should now be able to print.
If you have a spouse, you can switch to their DSUM buy clicking on their name at the bottom of the TurboTax window – they will get a yellow block by their name.
