In the personal info section where it asks if you earned money in another state, there is an instruction to answer no if you earned money in TX (and a handful of other states without an income tax).
The general rule is: your report all your income on your home state return, even the income earned out of state. You file a non-resident state return for the state you worked in and pay tax to that state. Your home state will give you a credit, or partial credit, for what you paid the non-resident state.
Since TX does not have an income tax, you do not have a non-resident return to file. But you still have to pay tax on that income to your home state. In other words, having worked in a state without an income tax does not get you out of paying state tax on that income, to your home state.
