First, the 5498-SA that you received in the mail is for informational purposes only; you do not enter it into TurboTax.
Second, line 14 on the 8889 reports all distributions from your HSA (and then some). You do not enter this amount, TurboTax generates it as it is completing the 8889 for you.
I do not know what you are referring to when you write "It says something abouy enteting line 14 of for 8889 tax return ".
Where do you see this and what is the exact question?
