Immediate annuity

I am ready to convert my 401(k) into an IRA. I am 61 years old and want to start taking annual distributions. The current balance in the 401(k) is $562,000 and I would like to withdraw 4 percent annually. Fidelity Investments is recommending a Guaranteed Annuity of $400,000 and the remaining in a managed portfolio fund (balanced). The annual fee for annuity is 1.90 percent of the balance and the managed portfolio 1 percent. These are the only fees. There is a 2 percent penalty if withdrawn within the first 5 years. Is this a good option, or should I keep the money in moderate conservative index funds? Emma, Las Cruces, NM
