TurboTax does not have an in-product feature that would allow you to print your deductions side by side view (for different tax years) from that page while you are preparing your tax return. However, you can press CTRL + P to print the web page(s) you are currently viewing.
Another workaround to copy the information from the webpage you are on would be to do a screen capture or print screen, paste the image in a Word document, then save and/or print it.
