If you elect the option to "print and mail" the return, the program will print all forms you are required to mail. Additionally, an instruction sheet will be printed too. That instruction sheet will tell you what additional forms you need to include in the mailing - such as a copy of any W-2's or 1099's you may have received in the mail. Finally, the instruction sheet will also provide you the address to mail the return to.
A physically separate instruction sheet will be printed for the state return. The instructions for the state return will not be the same as for the federal return. For example, you mail your state return to the state at the address provided on the instructions for the state return. Then you'll mail the federal return to the address provided on the instructions for the federal return.
Do not mix things up and mail the state return to the IRS, and vice-versa. If you do, then the recipient will "NOT" forward the return to the correct recipient. They will just shred it.
It's also highly recommended that if you mail your tax return(s), that you mail them via certified mail at a minimum, so you can track them for confirmation they were delivered.
Certified Mail only confirms delivery. It does not confirm the recipient actually received it.
Return Receipt Required (not requested) requires the recipient to sign for receipt of the mail and is confirmation the intended recipient received it. While it cost a few bucks more, in my opinion its the better way to go.
