Usually, your HSA contribution is reported in box 12 of your W-2 with the code W (Company Contributions to Health Savings Account. TurboTax automatically records this amount in the 1099-SA, HSA, MSA section. Code W reports the combined HSA contributions from you and your employer. If you had no distributions, then just enter 0 when asked by the program.
If you have questions about the contributions or about whether or not you have an HSA account, you should speak with your HR department at work.
