Depreciation calculations

I'm having trouble with the automatic depreciation calculations for our business tax return.  Last year's projected depreciation showed $11,700 on one of our vehicles for the 2024 year.  We're working on the FY 2024 return now and Turbo Tax is only showing $3,742 for the vehicle depreciation amount.  We had the vehicle all year, so don't know why the amount would be different than projected.
