@dmertz I am very sorry that I did not say it clearly in the 2 questions I posted last. These two questions were both on TAX which I need to pay before 4/17/18. The brokerage firm already calculated RMDs and did the distributions on 401(k) A as well as 401(k) B (after distribution, 401(k) B was rolled over to Traditional IRA). Before rollover I had no Traditional IRA. I would like to use your method above which had an example of $190,000 2017 year-end balance, to calculate my taxes. What I was not (and still am not) sure, is which DATE do I use for 2017 year-end balance on 401(k) A distribution, and which DATE do I use for 2017 year-end balance on 401(k) B distribution. Thank you for your help.
