"Can I make the remaining 401k contribution to the Traditional IRA"
No, the contribution limit for a 401(k) only applies to contributions made to a 401(k). Any ordinary contribution that you make to an IRA is subject to the IRA contribution limit.
Since you are over the $89,000 MAGI limit for being eligible to deduct any of your traditional IRA contributions but under the $150,000 MAGI limit where the Roth IRA contribution limit begins to be reduced, it would be beneficial for you ask your traditional IRA custodian to recharacterize the $200 traditional IRA contribution already made for 2025 to be a Roth IRA contribution instead and to make additional contributions to a Roth IRA to increase your contributions up to the limit (an additional $6,800 if under age 50 or $7,800 if age 50 or over, assuming that you have sufficient compensation to support the maximum IRA contribution for the year).
