Federal refund accepted but state refund rejected

Hi

 

When I e-file my taxes, both of them were rejected the first time because I needed an I PIN code that I didn´t have. When I found it, I filed them again but this time the federal refund was accepted but the state tax was rejected. There is no code or explanaition why this happened and I requested and extension until October 15th to fix it. The state was Wisconsin and I do not see why it was rejected. What should I do, please help me?
