On your 2025 tax return it will simply be reported as a rollover. The fact that the rollover deposit within 60 days doesn't occur until the calendar year following the year of the distribution has no effect on you you report the distribution and rollover on your 2025 tax return.
Note that the distribution from the 401(k) will have a mandatory minimum 20% withheld for federal taxes, so to roll over the entire distribution you would have to use other funds to replace that 20% (or more if you elect to have more than 20% withheld). Any excess tax withholding would become part of your 2025 tax refund. There is no mandatory tax withholding on an IRA distribution, but there is 10% default withholding unless you specify that something other than 10% be withheld (perhaps nothing withheld).
A distribution from the 401(k) does not involve the one-per-365-day period limitation on rollovers, but distributions from an IRA and rolled over to another IRA (other than Roth conversions) are subject to this limitation.
