Self-employed

i have narrowed down the problem. I am trying to create a return for my mother-in-law. I started a new return using my name address,etc. I then changed the personnel data field by field. Initially i was able to create a return without the TP-1029. However when i changed her birthday to "1921", I got the TP-1029.  It looks like their is a bug related to birthdate.  Please look into this.
