Vehicle depreciation error?

[Kea]

Is anyone else finding errors in the vehicle depreciation in ATX?

Client sold vehicle that was put in service in 2007. Cost was $35,253 and $17,500 special depreciation was taken in 2007. 2009 business use was 89.97%. Truck over 6000 lbs.

I calculate $2456. $35253*89.97% = 31717. Less 17500 = $14217 recovery basis. This number matches ATX. $14217 * 89.97% business use * 19.2% (3rd yr depr) = $2456. But ATX displays 40% depreciation rate and $1257 current year depreciation. Vehicle was sold 9/17/09, but I still can't match computer's figures.

Client bought replacement vehicle 9/21/09 for $13800 (used) and 2009 business use was 93.59%. At 1st ATX was showing the same 40% depreciation rate and $5166 1st year depreciation and that didn't change regardless of the amount I entered for Section 179. I closed program and reopened, changed truck to under 6000 lbs and back again. It helped, but still shows 40% depreciation rate and has a low value for current depreciation (like sold vehicle). With no section 179, 1st year depreciation should be 13500*.9359*20%=$2527. ATX has $1569.

Depreciation limits should not apply due to size, but even then I can't get to their numbers.

ATX problem or is it me? (I admit this has not been my best tax year.)

Thanks

I guess no one else had this problem. I'll just overwrite and go on.
