Okay, I have already e-filed one state return this way for 2018 (without paying for the federal) and it went through and was accepted. I'm assuming it sent the federal forms as well, because why would they let me efile the return if  the federal forms are required but not attached. Is there any way to check or verify if the federal forms were sent as well? Is there a check box anywhere in the software that needs to be check to include the federal forms or is it automatic? I don't mind paying for the federal forms if that's what it takes, but I don't want to pay for them if it's not necessary.
