Don't worry about it. It should be fine. And you can't change the past now.
The rules for vehicle are complex, and how much you can deduct using Section 179 or using Bonus Depreciation depend on several things, including the GVWR of the vehicle and the details of the vehicle itself (such as if it is a cargo van with a barrier between the driver and the rear, or if it is some other type of van).
Because of those complexities and I don't know why kind of van you have, I can't give super-specific advice. However, it probably isn't a big deal for several reasons. There are several options involved, and which one is best depends on your very specific circumstance. Working with a good tax professional is best because they can guide you through which are the best options for your circumstances.
