What tax year ?   1040EZ is no longer a valid form.  

there should be an option on the Federal Information Worksheet to force the 1040.

Must be an old tax year, 1040EZ has been gone for a few years. The program will default to the type of return required for the data youve entered, there is an option somehwere to always use 1040, even if they qualify for 1040A or EZ...I think its in the Fed Info worksheet somewhere.
