I received an RMD calculation from the TSP that is incorrect and Is 10% larger than it should be, as the TSP refuses to use the Joint and Last Survivor Life Expectancy Table when appropriate as required by IRS rules. I calculated my correct 2025 RMD and will file taxes using Tubo-Tax Deluxe. Is there a way for me to provide documentation of the correct RMD with my return so the IRS has the correct information?
