Deductions & credits

You will enter your 1099-SA. After you enter the HSA distributions from the form, you'll be to enter any contributions you personally made- see @KrisD15 's screenshot.  There, do not enter any contributions you made via payroll.  This will double count them because they were already reported on your W-2 in Box 12 Code W. You also should indicate that the amount withdrawn on the 1099-R was used for medical expenses (if they were in fact used for medical expenses, otherwise it is taxable.)
