Was the potential 2012 tax refund listed as an asset on your bankruptcy papers and exempted? If so, and the Trustee did not object within 30 days following the date your meeting was CONCLUDED with the Trustee, then it is yours to keep. Otherwise, it belongs to the Trustee.
You need to determine the above, including the date the 341(a) meeting was concluded (if it was concluded), in order to have your question answsered.
I have no idea what the "motion to object" you reference is about or who filed it, so I cannot express an opinion on that.
