What kind of 1099G do you have?  You might be in the wrong spot.   You do not enter it in the same place as a 1099Misc.

State or Local tax refund?  Federal>Wages and Income>State and Local Tax REfunds on Form 1099G

Government pension, taxable grant, etc?  Federal>Wages and Income>Other 1099G Income
