Prepared Pennsylvania Income Tax Return using H&R Block At Home software, which I purchased at Best Buy. It made a big error, offsetting gains against losses. That is not allowed by Pennsylvania. When I got a bill from the State, including penalties, I called H&R Block. They did not acknowledge the error and demanded a lot of paper and computer files on CD's. All I wanted to do was to email them a copy of the file and have them correct the error. They are supposed to be high tech. Next year I will use anything other than H&R Block.
