And when I opened them, every single Federal of them was blank, completely devoid of the values that I had filled in and saved. I do not know exactly how this happened, but I am not at all happy about it.
So I filled them in again.
Interestingly, the Illinois tax forms had kept their values. I have no idea why.
And I caught a six dollar error in calculation when I was filling in the forms again. So I had to tweak the values on the Illinois form anyway.
