Amended Federal and State return

[Johnfman55]

I get conflicting information on the internet regarding what forms need to be sent with a paper amended return for both Federal and State (New Jersey).  Some places it says to include only the forms (w-2, 1099, etc) that have changed while other places say to include all such forms regardless of whether they changed.  It appears that perhaps paper return versus electronically filed return causes the difference.  What is the truth about the forms to be sent  for a paper return both Federal and New Jersey.

You can review the IRS website Where to file paper tax returns with or without a payment? For mailing addresses. Include your W-2s and any 1099s that have tax withheld. Refer to the IRS Tax Tip HOW TO PREPARE YOUR TAX RETURN FOR MAILING for additional information.

To find out the address to mail your state return you need to check your State Department of Revenue website to get the address . Refer to the TurboTax Help article How do I contact my state's Department of Revenue?  and select your state.

For the federal amended return, include only Form 1040-X and any forms or schedules that have changed or are added. Do not include a copy of the original return. For more details see the IRS Instructions for Form 1040-X, especially "Assembling Your Return" on page 11.

For New Jersey see "Enclosures with Form NJ-1040X" on page 1 of the Instructions for Form NJ-1040X. Do not use staples, paper clips, or anything else to fasten the pages. Just put all of the pages loose in the envelope.
