I cannot continue my Federal Taxes (QTP)

So I am a Grad Student with a 529 College Savings Account, and I already entered in my 1099Q form under my income. After I finished up with my W-2s and my credits, I am approached by a page stating: "Other Income Statement: Qualified tuition program distributions - Taxpayer - You can't file just yet due to a recent law passed by Congress". And it's telling me to review my distributions which I had already entered, and I checked that they are correct. What Law?! Why can't I submit my taxes now, when I already have all of my documents ready?

Is anyone else experiencing this, because I would love an explanation. Also what did Congress even do?
