What mistake did you make? We cannot see your screen or your tax return.
Did you get a W2 from each job? What mistake?
You don't have to file if you only have W2 income under 12,950 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.
Filing requirements for a dependent
The Standard Deduction for an individual for whom an exemption can be claimed on another person's tax return is limited to the greater of:
…..$1,150 or
…..Your earned income for the year + $400 (but not more than 12,950))
So you would get a minimum of $1,150.
Did you file your return? Did you check the box that says you can be claimed on someone else’s return? You can be claimed on your parent's return if you are under 24 and a full time student. If you didn't say you were a dependent then your parent's return would reject.
