I am filing four state returns. If I say I am going to file by mail, the instructions tell me to mail copies of the other state returns with each state return.

On the other hand, if I say I am filing electronically, the instructions do not tell me to mail the additional returns from the other states.  If I e-file, are all the necessary returns for each state sent electronically? I am filing as a part year resident in TN and GA and a non-resident in AL and VA.
