941-X Do I need to submit if employee repaid net pay overpayment in same year and W-2 not created yet?

[michimochi1]

Employee returned overpayment of net pay within same calendar year (2020). As the employer, do I only need to complete Form 941-X to be refunded for the employment taxes (federal income tax, social security, medicare), and employer portion of social security/medicare taxes? Which box do I mark in Part 2, question 5, a-d?

I haven't issued the employee's W-2 yet so I believe I can just note the correct compensation on that.

Do I need to do anything else?
