Yes, part of your traditional to Roth conversion will be taxable because you had pre-tax funds rolled over from the 401k to the traditional IRA. Please be aware, if you had a value in any traditional, SEP or SIMPLE IRAs on December 31, 2021 with pre-tax contributions then each distribution will have a part allocated to the basis and a part allocated to the pre-tax funds. Therefore, each distribution will be partly taxable.
