I have received a letter in the mail from the irs saying I need to send my tax return and sign it to the address to the irs in Kansas City, does that mean I need to send my federal return or my state? and what is the tax return form I need to send? I thought I already did this but im guessing its not the right one since I got another letter in the mail. Im just wondering if you know because I haven't found anything on this
