I am just another long-time TTax user.
I did an amend years ago - it was a pain in the you-know-what.
Just to caution other users - I would have instead, if they are in a hurry, to finagle the answers as others (me too) have indicated.
You are reporting all of your income that way (most important), and you are also reporting your total RMD as well, just not per account as TTax has requested.
