The pop box on the right in your post states you either did not enter your Advance Child Tax Credit payments you received or you input the incorrect amount. The IRS matched up your input to their records and determined the change.
If you would like to see the details of the change you can Get Your Tax Record on the IRS website and request a transcript of your 2021 return.
