You can enter a W-2 for 2024 on a 2024 tax return. However, if the earnings were for only three weeks, it is unlikely to be enough to get much child-related credit. You will likely get back any amount that was withheld for federal tax from box 2. You might get a little bit of earned income credit. If you do not have more than $2500 of income from working, you still will not get the refundable additional child tax credit.
That credit is calculated like this:
Look at box 1 of your W-2. Subtract $2500 from that. Then take that number and multiply by 15%. That is your refundable amount --or "additional child tax credit" amount. If you did not earn at least $2500 you cannot get any additional child tax credit at all.
