I go through all the steps but "Print to mail" on the last page does not give a clean print to mail in. It has Duplicate/ do not send by mail" all over it. It is the same print as several pages before when you saved and printed to pdf.
Within the windows Standard edition, Print Return To Mail and Save PDF of Return to Mail both give me a clean copy without the Duplicate watermark. Are you sure you’re working with the latest update of Turbo Tax?
Please follow below steps to get a return printed without the watermark:
If you are using the EasyStep Interview, switch to forms by pressing Ctrl+R on your keyboard.
1. From the File menu, select Print, and then Print Return.
2. Click Continue button on a screen Save a copy of your return for your records
3. Click Save PDF of Return to Mail
4. Save the PDF file
I had the same problem. The issue is that until you choose "Netfile" it doesn't give you the option of printing a clean copy for CRA. When you do, it is actually fairly clear.
