I agree it would be great if Intuit had those things automatically carry over, but I wouldn't hold my breathe on Intuit changing things.

Accountant Man has a good point that it is best to be referencing last year's return anyways (and therefore it should only be very tiny amount of time to look at the divorce date or county), but assuming you want to continue doing it the way you are doing it, you might consider creating a spreadsheet with the information for all of your clients (county, divorce date and anything else).  That way you would have all of the information in one place, either for pre-season data entry, or to quickly reference while you are doing the actual tax return.
