The taxes you had withheld at the time of withdrawal, were only an estimated amount...or a fixed standard amount.....like your tax withholding for a W-2.
The actual tax assessed due to that 50k will be determined when you file your full tax return for 2022.
You get a 1099-R for it in late Jan or Feb of 2023....you enter that 1099-R into the software, and the 50k gets added to your income, and the tax withholding listed in the 1099-R will be used as a credit for taxes paid.
Your 2022 tax return will be the final accounting of all your income, and all your prepaid taxes and withholding for 2022....including that 401k distribution.
1) IF your total income, from ALL sources is low, then the $$ they withheld may have been too much and you might get a refund of some of it.
2) IF your total income, from ALL sources is high, then the distribution may have pushed you into a higher tax bracket, and the $$ they withheld may have been too little.... you might owe some more tax when you file.
