I'm trying to use the W4 calculator in Turbo Tax 2020. When I get to the screen to enter the federal income tax withheld to date, Turbo Tax does not allow me to enter anything. For me and my wife, both of the boxes are pre-populated with "0." and I cannot edit these values. It doesn't look like I did anything wrong in the calculator to lock out the entry boxes. Is this a bug in Turbo Tax? Anyone else having this issue?
