Yes, save everything to PDF and print out all forms just in case any State(s) require when you mail in your return a copy of your Federal. Make sure to sign and date everything and keep paper copies for your records. When you mail out, I tell everyone, be SURE to mail in Certified Mail / Return Receipt Requested so as to ensure you have a receipt for filing and a stamped date from the Post Office, as well as a return receipt from the I.R.S. and your State(s) Department(s) of Revenue showing that a person signed for your mailed in returns.
