Is there a way to test if e-file will work ahead of time without sending?

As I'm working on a return, I would like to know if there are issues that prevent e-file earlier in the process then at filing time.

 

Is there a way to test in advance and discover what entries might prevent that?

 

The obvious is "mark estimated" so no need to mention that.

 

But some attached statements or overrides may prevent e-file.

Are there other things as well?

 

Anyway, a way to show or find all blocks to e-file would be handy.
