State tax filing

I received the exact same letter with he issues of it not calculating the exclusion properly. Lines 4 and 5 in the GA return do not add up properly, so GA Dept of Revenue corrected the math and wiped out my refund. I now need to file an amended return to get my refund back.  Now I'm not sure if I can do this through Turbo Tax or if I need to file it manually to avoid the same error - do we know if this bug has been fixed?
