Sorry to hear you are stuck in that ridiculous TTX software PDF foulup.....the "First" printing option below, sometimes works (ignore the reason why they are doing this)...but the second one, below the triple-line, seems to always work.
First: Try the large PDF file creation in this FAQ starting at:
"In some cases, clicking the Download all forms and worksheets link (instead of Download/print return) in your Tax Timeline will give you clean printouts without the watermark:"
IF that doesn't work: then use the same "Some Things You Can Do" picture from the above FAQ, but instead click on the "Add a State" selection (you won't actually be doing that). Then when you get into your tax file, go to the top of the screen, click on "MyAccount" , then "Print Center" and Print or Save-to-PDF from that menu drop-down instead.
