Decedent estate return with nothing other than bond redemption interest of $140K taxable income.  Proseries calculates the tax as $55K. There is no supporting calculation for the tax in the program, when I  looked at government tables, I calculated the tax to be approx. $27K. Can someone please help me figure out where I can get the details behind how proseries calculates the $55K and how to make sure this is being calculated using the correct tax table.
