Thanks all for your responses! I understand why filing a 1040X is recommended. Creating the amended returns (1040X) for all these years is proving difficult, however. I am missing my copy of 2017 Premier and can't find it readily available! I had a couple more complex tax years during which I used a CPA rather than TT; if I wished to amend those years and generate a 1040X, do I generally need to enter all the data from the return into TT for that year, or is it possible just to generate the 1040X and the 8606 without recreating the entire return? Sorry--I've never done an amended return before!
