Relocation Lump Sum Repayment

Hi! I received a lump sum $10,000 for relocation from my employer. After taxes was taken out I received $7,035. Due to unforeseen circumstances I had to leave the company before my 1 year.

I am being asked to repay the $7,035 I received. What’s the implication of the $2,965 paid in taxes? Will I end up owing more taxes this year? Or will I get a larger refund due to the higher taxes already withheld?

Thank you in advance!
