Deductions & credits

Hello! To answer your questions:

Is the stipend your only income? Yes

Did you pay any foreign tax on the stipend? Yes

Do you file as a nondependent or dependent US Taxpayer? Nondependent/Independent US Taxpayer.

I earned between $20-$24k. When I type $20k, Turbotax is saying the tax is $497. When I type $24k, it is saying the tax is $1049.
