Thanks for your reply. In order to use turbotax, I bought a new computer since all existing computers at home were under windows 7 and turbotax even did not allow installation on windows 7. This is a brand new computer with windows 10 and I checked the trouble shootings listed in the link were not the case. I think it is a bug by turbotax software this year. Anyway, I already went through this step and just hope next year turbotax software can improve in this aspect.
