An HSA distribution—money spent from your HSA account—is nontaxable as long as it's used to pay for qualified medical expenses. After you enter your 1099-SA, we'll ask Did you spend all the money you took out on medical expenses? If you answer Yes, the entire distribution in box 1 of your 1099-SA is nontaxable.

However, if you answer No, the portion that wasn't used for qualified medical expenses becomes taxable income. This income appears on Form 8889, line 16 and Schedule 1, line 8.
