Leave all the boxes for state taxes blank on the 1099-G. Texas does not have a personal income tax so there will not be any state income taxes withheld on the unemployment compensation.
Or....I wonder if you are in the wrong place to enter the 1099G for unemployment. Are you in the spot to enter a state or local tax refund that is on a 1099G? You will not find TX there.
For your unemployment 1099G:
Unemployment compensation is taxable on your federal return.
You will have to enter a 1099G that is issued by your state.
Some states will mail out the 1099G. Or you might need to go to your state’s unemployment website and use the password, etc. that you have been using to certify for weekly benefits to get your 1099G from the state’s site.
Enter your 1099G in Federal>Wages & Income>Unemployment
Go through the screens very carefully, making sure to enter any federal/state tax you had withheld from the unemployment.
