I have the $40 (6%) on my 2020 taxes and I need to file an amendment for 2019 to pay the $40 for 2019. (Do I need to attach an explanation of why I'm amending somewhere? I saw that you're supposed to do that but I had Turbotax create the amended file and it didn't ask).
Correct.
No explanation is needed. The fact that you are including Form 5329 is explanation enough.
Oh, also I don't think I need to file a CA state amendment for this, but do I need to tell CA that I amended the federal one?
I'm not aware of CA having any state excess contribution penalty or anything that would change on your CA tax return.
