I'm receiving error code SCNTY-019-01. Turbotax program is not helping me fix my return or having me change anything. It wants me to file by mail now. Any ideas?

I've tried to e-file twice. Both times were almost instantly rejected. I follow the prompts from the notification email to fix my return, but it just tries to have me file again. I'm really trying to avoid filing by mail. I can just see getting rejected again in a couple months. This is my first time filing a state return.
