I'm unable to find a dropdown or tab in the Pro Series home base page that will allow me to attach, for example, a copy of a 7004, to a state partnership return that is going to be e-filed. How is the attachment accomplished? Also, a copy of the federal 1065 is supposed to be attached to the state return. If I print the state return, a copy of the relevant federal forms automatically print with the state return because I have checked the box on the print menu to do so. So, do copies of the same fed forms automatically attach to the state return during e-filing?
If it is part of the e-file requirement (e.g. send a copy of the federal with state) then it will e-file that way, normally.
There are a few forms that cannot be e-filed and must be manually attached to the e-file return. To attach a PDF of the form you want to go with the e-file return click the E-File menu button from inside the return you want to attach it to then click the Attach PDF. From there you can choose what file you wish to attache.
