I checked Turbo Tax about a week ago and found they haven't fixed the problem either. Two people from OR Dept of Revenue said that BOTH stimulus payments need to be subtracted. On ProSeries I can override the program and uncheck the error box when I efile and the return will be sent. I don't know about Turbo Tax. I was told by Dept of Revenue that if the return is incorrect, the taxpayer will receive a letter correcting the return with the second stimulus also reducing the federal tax subtraction when it's still above zero.
