certain "Payer" names cannot be too long for Iowa tax returns:
So
Go back to the Federal section, and EDIT the original "Payer" entry for every 1099-DIV you find there.
Make sure the name of the company that paid $$ to you (or to your account) has a shorter name.
Make it simple....chop some words off.....Fidelity Investments = Fidelity, or abbreviate.....Corporation = Corp, Company = Co...etc.
Similar edits might also be needed on various 1099-INT forms,
