Since you satisfied the RMD, it doesn't matter what you enter as long as it does not cause TurboTax to prepare Form 5329 Part IX to report a failure to complete the RMD. Entering the gross amount as both the amount required and the amount distributed is fine for preparing your filed tax return (although it doesn't help with your recordkeeping of the amount required to be taken). Form 5329 Part IX is the only place on your tax return that is potentially affected by these entries.
