A distribution from a "retirement account" should have been reported on a Form 1099-R, not a 1099-MISC. Entering a 1099-R in TurboTax would not have produced Schedule C and self-employment tax. Did you enter a 1099-R as a 1099-MISC?
What type of retirement account was it: a pension, annuity, traditional IRA, Roth IRA, 401(k), etc.?
