I'm sure one of the experts may see your question and chime in with solid advice, but for what it's worth, I would double check the mileage numbers and the date the vehicle was put into service to make sure a number wasn't incorrectly entered (funny enough I did that very thing last time where I entered my odometer reading with a digit swapped that threw some things off).
For curiosity sake, I looked at my 2021 taxes to see if anything stood out since I added my vehicle late in the season but I see that in 2021 there's only one line item (line 6) for miles driven in the year compared with the 2022 version that splits line 6 into two parts. I can't see any reason to do this and can only guess it's something the IRS implemented to torture us common folk 🙂
I'm not sure if you're doing this or not, but open the forms up (upper right corner of Turbo Tax and go to the Car and Truck worksheet under schedule C) so you can see everything easier than looking at the little pop-up window that opens when there's an error. I find this easier to look things over. Maybe you're already doing that. Anyway, good luck.
