Are You Notified if You Are Having Your Stimulus Check Withheld for Back Taxes or Student Loans?

loans

I received a notice already stating how much and when I will be getting from the IRS, but I’m wondering if that is how much I am supposed to get or how much I am getting. My husband has student loans in deferment right now and I thought they would withhold for that but they say I’m getting 1200 mailed on the 16th. Does anyone have more info on this.
