@smithjulie596 That's for a state tax return.
You would need to specify which state you are dealing with....then someone with specific knowledge of that state would have to answer.
I don't know that TTX software will allow you to attach any extra PDF/pictures
BUT
a)......Some states might allow you to E-file without attaching the documents, then you would hold on to those documents for a few years, to provide them only if the state decides to send you a letter asking for proof.
b) ...........Others may let you efile without them but require you to snail-mail in the proof documents separately to a special address after your efile has been accepted.
c) ...other states may require you to print/mail-file with the documents included.

...or, you may just need to call your own state's income tax department and ask how they want it done.
