Just to clarify my question: Since I plan to take the RMD as a one-time lump distribution along with withholding, this would make the quarter that this occurrence happens to be un-equal to the combination of income and withholding in the other quarters. In fact, I might over-withhold from the RMD to cover other income that had no withholding to make the total for the year be correct. I think you confirmed that having un-equal quarters for income/withholding is ok as long as the total withholding for the year matches the total tax due for the year, within $1,000. Correct?
