Was tax withheld on box 4?
If not, then NOTHING other then the box 1 and 2a amounts are even part of your tax return. The payers ID is only necessary to credit Federal tax withheld to your account and the IRS gets a copy of the corrected 1099-R also so amending might not be necessary unless the IRS send you a letter requesting it.
