did you get any reporting form? if not. I don't see how you can claim taxes he withheld(?) for you. you'll need to ask him how he reported these taxes(?) to the IRS on your behalf. if he didn't see a lawyer. without reporting withholding he would only be able to deduct the net paid and that's all you would report as income. by the way, if the divorce or separation agreement was entered into after 2018. it Is not taxable to you and not deductible by him.
