Deductions & credits

Thanks for your prompt reply. I have one last question (hopefully:)). Based on the eligibility criteria, I have a qualifying child. Between July and Dec I got advance child tax credit payments from IRS for half of the total amount. I was reading somewhere that if I didn’t live in the US for 6 months or more in 2021, I ain’t eligible for this and should refund this money back to IRS. Is that true ?
