For starters, all W-2 job related expenses, to include vehicle use, are not deductible.
For the rental, even if you claim vehicle use, you'll find the record keeping requirements alone to not be worth any savings - if there's actually any savings at all. Most likely, vehicle use on the SCH E won't make one penny of difference on your taxes.
Since the vehicle is not 100% business use for your rentals, you'll need to take the "per mile" deduction. That is, unless you can prove the expenses you claim are 100% rental use. While I won't say that's not possible, I will say you'll have a difficult time doing that - especially if ever audited on it.
With the per-mile deduction you enter your vehicle information in the vehicle expenses section. The program (not you) will figure your deductible expenses, including depreciation. Note that for 2023 the per-mile deduction is 65.5 cents per business mile driven. Of that, 28 cents per mile is depreciation.
Now I've got three rentals of my own, and I did the math many years ago and found that claiming mileage was a complete waste of time, as it didn't make one penny of difference to my tax liability.
However, when you sell the vehicle, you are required to recapture all depreciation taken and pay taxes on it. Now realistically, even after recapturing depreciation on the vehicle, more than likely you're still going to show a loss on the sale. So in the end, it's all a wash and really not worth the time, effort and record keeping.
