But...Like I've already said above...the 2019 amendment software won't be available until around the end of the month.  

The 2019 Amend instructions should be available by then...then you will have to start the "special" amend process, insert the missed 1099-R (and anything else you missed)  print out the amendment forms, and mail them in yourself at the Post office...with a check if you owe more.
