I received a travel voucher for expenses for when I was in the military. Where do I enter that information in this program?

You don't need to enter any information from your military travel voucher.  All the military income information you need to enter will be on your form W2.  Enter that form W2 information just as it reads into TurboTax. Any taxable income will be in box 1 on that W2.  Any excludable moving expenses for military moves will be coded P in box 12, for example.
