I didnt file in 2018 either. But i filled a 2019 tax return in february. Thats what they went off of. If your getting the "TRY AGAIN LATER" message then try putting the address exactly the way it is on your return. All the caps spaces EVERYTHING identical.and make sure to wait a full 24 hours before you try again...because it will lock you out and give you the try back later error. It will tell you your info is not on file. Thats what i did and i got in finally. The 24 hour thing is likely what it is
