I'm retired in 2023 from federal civil service. box 9b is blank on my CSA 1099R. Turbo tax is asking for plan cost. I put into the pension for over 30 years. What do i put for plan cost? From what point? I contributed Jan thru July and retired August 1, 2023. Should I just add up what I put into the pension in Jan thru July 2023? There were no contributions after August 1, 2023. So do I put zero? So little instruction for this simple question in Turbo Tax.
