The only way to know if you need to pay taxes is to fill out a tax return. If you have federal tax withholding and don't owe any tax on your tax return then you would have to file a 1040 tax return to get s refund of the taxes withheld.
Are you a dependent?
You don't have to file if you only have W2 income under 12,400 but you can file to get back any withholding taken out in boxes 2 or 17. But you don't get boxes 4 or 6 back. If you got a 1099Misc or 1099NEC you have to file it as self employment income no matter how small the amount.
