I am over age 59½ and have had a Roth IRA account for more than 5 years. Starting in 2025, I designated all of my contributions into my employer’s 401(k) plan as Roth contributions. If I decide to retire before I have met the 5-year requirement for the Roth 401(k) and roll over this balance to my existing Roth IRA account, which 5-year clock applies to those former Roth 401(k) dollars?
