Is there anything else I can do to file mo state. Says it's started but every time I go through state it always says started and won't let me complete it.

Yeah mine is doing the exact same thing and I need help with this answer too!

What happens when it will not allow you to complete it? 

It could be due to an unsupported for e-file. You can view if you have a form not supported here. 

Please let us know if you need further assistance.
