Hi There! I just mailed my 2017 amended return as the previous user mentioned, download the 2017 TT and triple and quadruple check it. Add your DD info and make sure you sign everything.
I HIGHLY RECOMMEND that you mail both your federal and state return via certified mail keep receipts of everything. USPS is letting returns "slip thru the cracks bc of high volume". I would've been screwed had I not been proactive. I watched this video and it helped me a lot.
Good luck!!!
