When sending your tax return by mail you must click on print to mail and there should not be any watermarks(duplicate) on it. This Is the condensed return that they need. 

Thanks but the question is after I have filed.  I filed a revision to the original filing and provided the information about the changes in their requested format. I had to send the revision by mail since it included sharing of pension with spouse. CRA requested that I file a few of the schedules related to the revision. I tried printing specific schedules using Turbo tax using print to mail. I am assuming that Turbo Tax registers the return as filed thus the water mark of duplicate copy.  Would I have to create a totally new return in order to get around this problem?

If you save a copy of your return on your computer you can print from the PDF. If not, follow these steps here. 

If you are still having issues with duplicate/watermarks- please contact our customer service for assistance.
