On the deductions and credits section, click update next to 1099-SA, HSA, MSA.
When asked what kind of account, choose that you had an HSA account.
Click Yes when asked if you used your HSA to pay for anything in 2024. This is where you would enter your 1099-SA.
Later on, you would need to indicate that you didn't have an HDHP at all in 2024. This allow you to bypass the questions about coverage.
