No -you do not.
Is there a QDRO (qualified domestic relations order) and the ex spouse gets their own 1099-R or do you receive the payment and give some to the ex.
If the first, then you have nothing more to do since the ex is responsible for reporting their own 1099-R.
If the 2nd, then you are responsible for all the tax and it is up to you to collect the spouses share of the tax (that the court order should specify) or reduce the amount that the ex receives minus their share of the tax. If the court order is moot on the tax then talk to your divorce attorney since the court order should specify how the tax should be paid and by who.
