Omitted Form 8889 on Submission, Later found 1099-SA

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?

Yes, you should amend just so the IRS is not questioning if the money was used for medical expenses. If you do not amend then you might see a tax bill one to two years down the road. If all withdrawals were for medical purposes there would be no change to your tax income but the Form 8889 would confirm the facts,

If you want to make changes or add a document to a tax return that has already been submitted, you should follow these guidelines.

You must first wait until the initial return is completely processed.
You will have to use the same TurboTax account that you used for the original tax return.
Once you begin your amendment, you'll see your original return. 
The refund calculator will start new at $0 and only reflect the changes in the refund or tax due
Only make changes to the areas of your return that need amending.
You have three years from the date you filed your return or two years after you paid the tax due (whichever is later) to file an amendment

Select your product below and follow the instructions. Be sure to read all the instructions carefully, before you begin, so that TurboTax knows the original numbers and the changed numbers for your amendment.

Thanks for that information. It turns out I've been using that form since doing my 2019 taxes. Not sure how I missed it this time. Oh well. No biggie it appears.

That said, when I went back into TT it saved the changes I made to see if my refund would change. I did not tell it to save anything, but it did anyway. Will that mess-up TT knowing the original numbers when I submitted?

Thanks again,
