"Check this Entry" is asking for a date, but just asks over and over and over. Is the form broken?

It is asking for a Date (from my stock portfolio), but when I enter the date, formatted correctly mm/dd/yyyy and I hit continue, it just asks me again.  I've musta answered this same question a few dozen times now.  I get the feeling this form is broken and I cannot answer this correctly.  What can I do.  it will not let me e-file until this is "fixed", but I cannot fix it.
