The income was from the United Nations which does not issue W-2s so I entered the income on form 4852 (substitute W-2). The TurboTax program did not calc Social Security or Medicare taxes and I didn't spot that problem and went ahead and filed the tax return with that error which was later reported back to me. I have opened an Amended Tax Return but can't find a way to calculate SE taxes on the 4852 income.
