PA TAX question...please help!!!?

I worked in texas for 2 months this summer (they don't have income tax there). I should claim that on my PA tax form right, as taxable income? At first, i wasn't going to because there's nothing in box 16, but then I realized that all the other w2s had taxable income, from both PA and IN. This made me pay 167 instead of 29. Did I do the right thing?
