State tax filing

Thanks!   I was going a little nuts as TT was computing a little less than what the IRS Sales Tax Assistance was coming up with.    My Village has a 3.5% local tax but the IRS is showing 4%    I finally caught it at the bottom where I saw my zip code is averaged in with other zip codes hence the higher percent.     I left it at 3.5% in TT.   ($1095 me VS $1150 IRS)
