roth withdrawal after 65
Hi I've never posted before, but hoping someone can answer this question. I had a roth 401k (for 5 years) that I transferred to Vanguard and then shortly thereafter I withdrew it to purchase a house. I still have two other roth accounts at Vanguard that I have had for at least 10 years. I am over 55 and was over 55 at the time of the Roth ira withdrawal. Vanguard's 1099 says taxable amount not determined. Turbo tax is making me do calculations as to all of the roth contributions that I have ever made that are still not distributed. Does this sound right? To figure that out I will have to go back almost 30 years. I know what amounts are currently remaining in my roths, just not how much of those is from contributions. I think this exercise should only be relevant if I was under 55. Anyone know the answer? Thank you.
