Why does my tax return print with a "Do Not File" watermark?

If you print your tax return in the Preview area of the Print & File section, it will print with a watermark that reads "Do Not File." This is because returns printed from this screen are only meant for you to preview before you e-file your return (if you choose to file by mail, this preview screen will not appear).

Here's what to do: Keep going through the e-file process until you have transmitted your return. Afterward, you'll be able to print the actual copy of the return you filed -- without the "Do Not File" watermark.
