This is the most useful thing anyone sends, and it gets read. The site exists to be right, and the people most likely to spot an error are the ones holding a payslip from the state in question.
What helps most, in rough order:
You do not need all of that. "Ohio looks about three hundred dollars light" is a perfectly good report and has been enough before.
Questions about your own tax position, what you should withhold, or whether to take a particular job. Those need somebody who can see your circumstances and who is qualified to advise on them, and that is not this site. See the terms of use on why.
Every state page names the document its figures came from and the date it was last checked, and links to it. If a figure looks wrong, that link is usually faster than an email, and if the document disagrees with the page then the page is wrong and worth reporting.
