Your disposal of your house is a tax event. Disposition means lose control. Getting an insurnace payout in 2024 is not disposition (loss of control), therefore it is not a tax event in 2024. Insurance payout for your calsulty loss portion is not taxable. However, other payout such as lost income might be taxable.
As for how to deal with capital gain when you sold your house in 2025/2026, I believe the insurance payout lower your cost basis, but if the payout is more than the cost basis, so that your adjusted cost basis is negative, I am not sure how that works. Maybe consult an accountant.
