While I was doing my taxes, TT asked me about my HSA. It asked if I spent any of it, which I did. Then it said I should have received a 1099-SA. I did not know where to look for it, so I submitted a question to Fidelity. It took them 5 days to respond, and it turns out they do, indeed, provide one.
So I went back into TT and entered the info from the form, but it didn't change the amount of my return.
Do I need to amend and re-file with Form 8889 included?
