So, essentially, I should only be worried about the account where the money was withdrawn. If I decide, in the future to withdraw money from the Roth 401k, will the answer to the original question, What counts as a "Prior Year Roth IRA Contributions"?, would I add up all the contributions I made to only the Roth 401k? Even though I have transferred some of them to the Vanguard Roth IRA?
