On these bigger one-time payments often a larger percentage is withheld. As I understand it, it could even be obligated by the IRS to do it like this.

So you will have to wait to get it back.

However, when you get a new job in 2023, you could aim to under-withhold some taxes there, so that every paycheck is a bit bigger, and after the end of 2023 you get a smaller refund. (Use the IRS W4 calculator to get the "correct" amount of taxes withheld, taking into account all that you earned and will earn in 2023 and the amount of money that was already withheld).
