For 2023, if you were eligible for all of 2023, your limit was $3850 for a single plan. You would show the $1350 contribution on line 2, $3850 limit on line 3, line 8 will be $3850, your employer contributions on line 9, line 13 zero, then see the instructions because you over-contributed so you have to go to form 5329 Part VII. The excess itself is not shown on form 8889. The excess is on line 48 of form 5329.
Did you ask the plan for a removal of excess, or just a regular withdrawal? If you asked for a removal of excess and they did not return any earnings, then I would assume they don't pay interest? If you asked for a regular withdrawal, that needs to be corrected.
On your 2024 return, you're going to report just the employer contributions, and the form will calculate that you get no additional tax deduction (because the employer contributions were already excluded from your taxable income). The excess is reconciled on form 5329.
