The 10,000 Max refers to the total of property taxes PLUS any state income taxes.
So if your state income taxes paid during 2021, either thru withholding, or thru quarterly estimated payemnts.....if that total exceeds already exceeded 10,000, then you've already reached the max even though you haven't entered any property taxes. Like, state withholding already entered with W-2, W-2g or 1099-R forms entered in the Wages&Income section.
