Won't show error to fix

Help. Trying to file today before I return. When TT reviews my returns I get an error message. I get the message "Dividend Income Worksheet: Payer has too many characters." Then I hit continue continue botton nothing happens and the software seems to freeze.  I went to all my forms and there were no error symbols on any of my forms.  I then went to file and it is trying to force me to file one of my state returns by paper (the Iowa return for which I am a non-resident with some limited farm trust rental income).  My resident state is NE.  How in the world do I find the error?  I went through all my 1099 Div and didn't see any payer number problems.  I use TT Advantage Premier desktop.
