Amending my 2022 and 2023 tax return to include my child's SSN for child tax credit

Hi all, I have an L1 working visa. I filed my 2022 (with extension) and 2023 tax returns (without extension). For the child tax credit, since my daughter didn't qualify for SSN at the time, TurboTax led me to apply for ITIN because I included the child tax credit in my tax return. Along with my tax return, I included a W-7 form to request ITIN for my child. There were a few back-and-forth mails between me and the IRS on the additional evidence for my child's ITIN. Even though I provided everything the IRS asked for, they didn't issue ITIN for my child (I know other L1 visa holders whose children have ITIN). I was made to apply for my child's ITIN 4-5 times from scratch. Even local IRS office employees were perplexed that my child wasn't issued ITIN and couldn't confirm why. Due to a recent status change, my child got SSN. Can I amend my 2022 and 2023 tax returns to include/update SSN and claim the child tax credit today?
