The Federal Identification number is located under the Payer's name and address on the left side of the Form 1099-R.
I just filed my taxes yesterday with a 1099-R. The TIN or Federal ID is in Box 7
This is an official IRS Form 1099-R. Please refer to the form. Box 7 is specifically for entry of a Distribution Code.
Please let me know where I can find my federal ID number?
You personally do not have a Federal Employer Identification Number unless you applied for an EIN from the IRS.
You have a Taxpayer Identification Number which is your Social Security number or if you are not eligible for a SSN then it is the ITIN issued to you by the IRS.
