Should i need to just print all the tax return documents and mail it to them or any other documents needs to be attached ( extension filed and tax due paid).

If you are not e-filing then print the return to mail.  It will print with instructions for mailing including the addresses to use for federal and state returns.  You need to attach your W-2's and any 1099's that show tax withheld.

And of course, you cannot print until your TurboTax fees are paid.

 

Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS and/or your state received the return.

Is there some reason why you are not e-filing the tax return so that you would not have to print and mail anything?
