Hello, is there any way to see what forms are being e-filed before you submit?

Many have asked, we've never seen anything official.   

Logic would suggest that anything required and included in the "Filing Copy" would be included with the Efiled return.

I wouldn't think that supporting statements get efiled but I'm careful not to put down anything I wouldn't want the IRS to see.
