If you're e-filing, then absolutely no 3rd party forms are transmitted to the IRS or state, and none are required to be.
Now I have heard of situations where some 3rd party form may be required to be included with the e-filing. But from what I understand the program will tell you that and give you the option to import that form in PDF format *IF* you have a scanner. I don't know the facts on that, as I've never personally had to deal with it. I've just heard such stories very rarely.
Also, if the taxing authority requires some 3rd part form that you may have forgotten to include, then they will send you a letter via U.S. Mail specifically requesting it. This is no big deal.
The IRS/State are not going to send down black hawk helicopters to hog tie you, carry you to the IRS dungeon and drop you there just because you forgot something.
