In which section does it ask if I have an HSA? I am on a plan with one via my mother but cannot find it to change it because I did not make contributions to it.

The HSA is handled in 3 parts in the TT program :

First the contribution:

Next the limitations screen to confirm you are eligible to make the contributions:

Until you complete the HSA portion of the TurboTax interview to establish your eligibility for an HSA contribution, TurboTax will treat the amount entered on the W-2 form as an excess HSA contribution.

Are you saying that you are covered by your mother's High Deductible Health Plan (HDHP)?

An HSA (Health Savings Account) is a separate financial account that the owner uses to pay for qualified medical expenses with tax-advantaged dollars.

If your mother has the HDHP coverage from her employer, then it is likely that she has an HSA. If you are a dependent, you can't qualify for an HSA anyway.

If you don't have an HSA for yourself, then you do not need to report anything.

If I have misunderstood your situation, please come back and tell us what your situation is.
