Thanks for the response, April 18th it is. On my return there are four separate 1040-ES payment vouchers that add up to a good deal more than I owe per line 78 for the federal portion with dates ranging from April 18th all the way to January of next year. I want to pay what I owe only, and all at once, but it looks like Turbotax has other plans. Am I correct to assume that Turbotax has set it up so I have to make payments throughout the year totaling more than I actually owe, and if so, how do I stop that process and pay lump sum?
