I checked my refund status on the IRS app, it says "approved" but says also "may be reduced due to (etc reasons if you owe money)" Is this normal or am I being garnished?

My disabled son was declared "overpayed" by social security, I've been working 2 jobs to pay this mistake off while in appeal status with them, can they take my taxes?? My ex husband owes back child support also, but we were married last year, is that a factor? I'm just trying to see how much money I'm getting from my refund.
