State tax filing

State mandatory taxes generally flows from box 14 of your Form W2.  It sounds like there might be a decimal point out of place and you should review those entries.  Also, it shows you are using the desktop program.  You can switch to the Forms Mode and check for the State and Local Tax Deduction Worksheet (line 17) to see if that number appears there also.  

Also, state mandatory taxes are deductible taxes that are imposed on you by the state that are not direct income taxes (such as unemployment or disability insurance payments that go to the state).
