OK ... YOU have a SS# not an ITIN. If the 1099-R was issue to YOU in your SS# then there is no need for an estate return to be filed. Enter the 1099-R on your personal amended return.
Now if the 1099-R was issued in the name of the estate in the estate's EIN then an estate return needs to be done. If you are unsure of what needs to be done then use a local tax pro that you can talk with face to face.
