TurboTax has not way to tell if you omitted income. It can't see the Form 1099-G on your desk that you did not enter. It has to rely on you to enter everything. Not entering all of your income is an issue that TurboTax cannot detect.
Form 1099-G is used for several types of income. People sometimes get confused and enter it in the wrong place. If you mistakenly entered it as a state income tax refund instead of unemployment, it might have been omitted because in most cases a state income tax refund does not have to be reported. Again, TurboTax can't see your 1099-G. It has to rely on you to enter it correctly. If you entered the 1099-G as a state income tax refund, TurboTax has no way of knowing that that is not correct.
If you entered your 1099-G correctly, the unemployment income will be on Schedule 1 line 7 in your 2022 tax return. The total from Schedule 1 line 10, which might include other types of income, flows to Form 1040 line 8.
