Form 5329 should not have been sent separately. You could prepare your tax return as if that form had not already been sent, resulting in an identical Form 5329 with explanation being included in your tax return. Alternatively you could tell TurboTax that no RMD was required so that TurboTax will not include a Form 5329 in your filed tax return. I'm not sure which approach would be less confusing to the IRS.
