I have applied ITIN for my child along with Federal TAX return filing in 2023. The ITIN got rejected with the reason that I haven't claimed child tax credit. This happened as the checkbox "Credit for other dependents" was not selected in 1040. I was asked by the IRS to send the documents via mail for ITIN and I received ITIN for my child. But, the child tax credit $500 was not refunded in 2023.
I'm planning to AMEND 2023 returns to get the child tax credit. Can someone guide through the process?
