I have a correction to my earlier reply. Form 5329 Part IX has changed for 2024, so the recently released version of TurboTax now has changes to the way that TurboTax handles the determination of a requirement to file Form 5329 Part IX. The developers made a mess of it for cases where the individual has more than one account that requires RMDs to be taken. If all RMDs were completed timely, it's possible to get the correct result by manipulating the numbers (entering as the required RMD no more than the gross amount of the particular distribution) such that TurboTax does not prepare Form 5329 Part IX. However, for someone with multiple independent RMD requirements for different accounts and only some RMDs were missed, TurboTax prepares an incorrect Form 5329 Part IX because TurboTax fails to include information about RMD amounts that were satisfied in full. This causes the Form 5329 to be incomplete although the correct penalty is calculated.
