Car adjusted basis potentially incorrect. How do I do this?

TT Deluxe Desktop version: I owned a car since 2021.  I sold it this year half way through the year.  I traded it in for 20000.  I bought it for 30054.  I used it for 7.28% of the time for business.  I tracked my mileage every year and used standard mileage deduction. 

Adjusted bought price 2188

Adjusted sell price 1600

Depreciation (from mileage calcs each year) 1130  -It also tells me depreciation allowed is 1239 (might be some limit ), but this is still close to 1130. 

The gain should then be approximately 398$.

 

TT is telling me my gains are $1349 ordinary and $251 long term gain.   ACK...that doesn't seem right at all - or am I missing something?

 

I've read that TT doesn't calculate variable use each year.  Maybe that is the issue? Do I then click to convert to 100% personal use, and then just use property disposition?   Can someone provide me with a few more detailed steps to get this right - or is this a hiccup that needs to be fixed in TT?
