Withdrawals made in 2023 are only reported on a 2023 return. You need to have the 2023 program installed on your own computer, you can't do it online. Withdrawals made in 2024 are reported on a 2024 return only.
401k withdrawals are always subject to regular income tax. There is a general exception to the 10% penalty for early withdrawal for family emergencies, but only on the first $1000 of the withdrawal. And, you can only use that exception once every three years unless you have made more than $1000 of new contributions to the 401k between emergency withdrawals. The rest of the withdrawal is subject to the 10% penalty. There are other specific exceptions if you use the money for certain expenses, listed here. But they don't seem to apply to you.

It probably would have been better to borrow the money from the 401k. You can generally borrow up to 50% of your plan balance. Withdrawals are not taxable unless you default (stop making payments). Payments must be made by payroll deduction and can usually be spread out over 5 to 10 years.
