the CTC doesn't go into effect until 2021 but advance payments should start around June or July 2021. as for refunds for UC. no one, not even the IRS can tell you. there are millions of unprocessed returns. at one point the IRS stated that it might take all summer to make refunds to all taxpayers who filed returns that did not reflect the nontaxable UC. do not submit an amended return that could actually delay your refund.
