Each box in the state area has a question mark you can click for more information.
10a
You should have a state abbreviation in box 10a if you have an amount in box 11.
If box 10a is blank on your form and you have an amount in box 11, enter the abbreviation of the state that issued your unemployment. Do this even if box 10a is blank on your form.
If you don't see boxes 11 and 10a, or if they're both blank , that's okay. Not all states tax these benefits and may not include these boxes on the form (or may leave both boxes blank). If that's the case, you can leave them blank here.
10b
While the federal government considers unemployment as taxable income, not all states do. If your state taxes unemployment income, you'll have information in boxes 10a and 10b on your form.
Use box 10b to enter the state identification number shown in the same box on your 1099-G.
If your state does not tax these benefits, you won't see this box on your form and you can leave it blank here.
