1. Your parents will still claim you as a dependent, on their return. This assumes you were a Full time student for parts of 5 months.
2. You must file a tax return of your own. You will check the box that says you are a dependent on someone else's return. That will not reduce your refund, thanks to the new tax law (it did in the old days [pre 2018]).
3. You do not show that you paid tuition, on your return. But, your parents claim that tuition, on their return, even though you paid it.
4. In January, you will receive a form W-2 from your employer, that contains all your income and withholding.
5. There is little you can or need to do to maximize the tax refund. Students, with earned income, get a standard deduction of $12,000, so only $2000 of a $14,000 income is taxed. $2000 x 10% = $200 tax. You could make a $2000 contribution to a traditional IRA to reduce that to 0.
