How do I print print this return out For my deceased husband to send it to CRA without it having the duplicate stuff on the front?

There is no way to print a copy of your taxes without the watermark after you've Netfiled.  (This system was created because according to the CRA, many people were apparently Netfiling and then sending in printed copies. This was causing problems at the assessment level.)

Here are instructions on how to print your return without watermarks.

The option to print a tax return becomes visible only after you pay for that specific tax return. After you pay, the FILE menu lists the print options available to you. To print for the purpose of mailing to the CRA or save a copy for your own records for your current tax return, follow the directives provided below. 

Two options for printing; 

a) one is to print and mail to the CRA which will provide you with a PDF with no watermarks, or 

b) you can skip the print & mail and click continue which will give you the option to print for your own records (with watermarks) before you Netfile. 

After payment has been processed, in the side menu, select FILE, and then select Print & Mail your return to access the PDF without watermarks. 

On the screen select the link to open a PDF copy of your return, which will download to your computer automatically, open the PDF and click on Print, this will be the copy you would send to the CRA without the watermark on it. Hit Done. You will then be directed to download a copy with watermarks for your own records.

Thank you for choosing TurboTax.
