Adjusted Gross Income (AGI)Reject Code IND-031-04

First time e-filing, filled out everything correctly and received this error code Adjusted Gross Income (AGI)Reject Code IND-031-04 and well, both my federal and state taxes were rejected. I filled out the form with correct gross income, so getting this error just doesn't make sense to me. And I must fix this "error" and re-send, but how do I fix it?

Thanks
