Agreed, TurboTax's sanity checking of Percentage of Income seems to be broken. The not so helpful line of instruction says it needs to be between 0.000000 and 1.000000, but in reality it gives an error unless the value is between 0.0001 and 99.9999! YCinMA, you want zero, and I want 100, neither value is accepted!
Intuit, please fix asap!!!
