The $7163 is misleading. It is the maximum you COULD have contributed before you went on Medicare; since you contributed $0 before going on Medicare, you cannot contribute now.
However
Eligibility for an HSA is determined for each person individually, not for a married couple as a single unit. If one spouse has a qualifying HDHP (such as covered by a family plan) and no disqualifying insurance, they remain eligible to contribute to their HSA. Their eligibility is not canceled just because the other spouse enrolls in Medicare.
If the HDHP covers more than one person, such as both spouses, it is considered family coverage. This allows the eligible spouse to use the higher family contribution limit, even if the other spouse is on Medicare and cannot contribute.
There's a bug in TurboTax that takes you back to your screen rather than calculating your spouse's maximum.
If you withdrew nothing from your HSA for MEDICAL expenses (no 1099-SA) in 2025, you can delete your Form 8889-T because with it showing nothing, it will not be included with your e-filed return.
Another workaround would have been to do your spouse's first to calculate her maximum and then yours.
This means your spouse can contribute $8550 times 75% + $4300 times 25% + $1000( being 55 or older)
If my math is correct, that's $8488. Further, you will need to enter the actual contribution to her HSA by 4/15/2026 on her HSA Form 8889.
You need to indicate family coverage for the first 9 months and then self-only for the rest of the year on her Form 8889 to get the correct answer
