This is definitely a bug. You can't enter $1 on the error screen. You have to go to your federal income page where it shows your wages, stocks, etc... When you click on your stock info it'll take you to the form itself where all the info can be manually changed. This is where entering $1 worked for me. If you were on this same screen and it didn't work I don't know what to say. You could try putting in 0 or leaving it blank on that form but $1 is what finally fixed it for me.
