My residence is in SC but I worked the full year in LA. Why am I paying state income tax to both LA and SC?

[sdonahu]

Or shall I say is it correct for me to pay taxes to both states or not?

It is correct to pay state taxes in both.  Your state of residence can tax all your income, regardless of where you earned it.  A non-resident state can tax your earnings from physically working within its borders.

You can take a credit on your home state return for taxes paid to the other state, so you won't be double-taxed.

In TurboTax, complete your non-resident state return before you do your home state return, so that the credit flows properly.
