Without reviewing your Bankruptcy Petition and the documents related to the Garnishment, it is impoosible to give a definite Answer; however:
Your Bankruptcy Attorney should be able to easily handle the matter for you - without the necessity of any further Motions filed within the US Bankruptcy Court.
If you do not have a Bankruptcy Attorney; i.e., you filed and conducted the Bankruptcy matter pro se (by yourself), the letter together with the Notice of Commencement of Case, the Discharge, the Order Closing the Case, and the pertinent Schedules showing the Exemption of the garnished wages should suffice - if the garnished wages iccurred within 90 days prior to the date of the filing of the action.
