State tax filing

My issue is that I cannot file my state taxes. My federal was accepted and I received that very easily. However when I try and file for my state, it’s always the same.
First I was told to wait for the 540 form and I would be notified when that would happen. I received an email from TurboTax on January 31st saying it’s ready. I went to finish filing but it would not let me. 
I have been continuously trying to submit my state taxes and it always the same issue:

“we're sorry, there was a problem while processing your return. please retry to verify your return was sent.” 
I have checked and rechecked all my information to see if that’s the problem. I even had other people recheck my information but still the same issue. If it’s really just California being slow I wish it would make that more clear because this is frustrating and confusing.
