When my Father passed in 2019, his traditional IRA had nondeductible & deductible parts and the deductible parts were tracked by Forms 8606 before he passed. His IRA was inherited by his trust, and the annual RMDs from this IRA now go to beneficiaries via Forms K-1. However, when using TurboTax to file my Father's final return, and his estate return, there is no option to include Form 8606 or to otherwise address the nondeductible portion of his IRA.
How can the beneficiaries avoid double-taxes by paying taxes on the nondeductible portions of their inherited RMDs when they receive them from the estate?
