The IRS has not yet started accepting e-filed tax returns. They are scheduled to begin on February 12. There is still a chance your return will be rejected. If it is, you can add your 1099-SA. If your return is accepted, you can do one of two things: 1) File an amended return, or 2) Wait for the IRS to send you a letter proposing an adjustment to add $686 to your income. You can respond to their letter and explain that you received Form 1099-SA after you transmitted your return, so you didn't (correctly) file Form 8889.
I would wait to see if your return is accepted, and if it is then wait until you have received any return you are expecting, and then file an amended return. To file an amended return TurboTax, see:
