Are you manually entering your HSA contributions made through payroll in the HSA entry in TurboTax? If so, you shouldn't do that as you will be double-counting your contributions since it was reported on your W-2 Box 12 Code W. You also need to make sure you have indicated you have a high-deductible health plan all year.
According to Why am I showing an excess HSA contribution?, the 2024 maximum for both employer and employee HSA contributions was $5,150 if you were 55 or older at the end of 2024 and are covered by an individual (self-only) HDHP. If you were older than 54, check these entries:
- Click on Federal Taxes, Deduction & Credits
- Choose "add/edit" HSA, MSA Contributions
- You will see a page titled "Your HSA Summary" which will show any deductions already computed from your W-2
- Choose Edit, Check the box for HSA, Continue
- You'll now see a screen that says "Here's what we have so far" with the information from the 1099-SA, choose "Edit"
- After the entry screen for the amount distributed, $4,202, continue and when it asks "Did you spend your HSA money on medical expenses only?" answer "Yes", if accurate.
- Choose done and continue until you get to a screen that says "Let's enter your HSA contributions"
- In the box "Any contributions you personally made (not through your employer)" DON'T enter the amounts you contributed through paycheck withholding. It has already been considered through your W-2 entry.
- Continue on, and if you were covered by Medicare, you will need to indicate what months this was the case, as your contributions will be limited.
- Next, you will be asked if you were covered by a High Deductible Health Plan (HDHP) in 2024? You need to have been covered the whole year to be allowed to make the maximum HSA contribution
