Assuming you never actually worked in GA:
That income will be taxable by both IN and CT. It will NOT be taxable by GA.
Taxable by IN because that's where you actually performed the work. Taxable by CT because your home state can tax ALL your income, regardless of where it was earned.
You'll file a non-resident IN return in addition to your regular CT return. You'll be able to take a credit on your CT return for the taxes paid to IN, so you won't be double-taxed on that income.
In TurboTax, it's important to complete your non-resident return BEFORE you do your home state return, so that the credit flows properly.
