My client is claiming a dependent who was claimed by other last year...so other received the CATC based on 2020 tax return.  Other will not file this year.  My client will then receive the full CTC because she did not receive any ACTC or do I enter the amount of ACTC other received last year?  If I enter 0 which is correct...will this create and issue of double dipping?

Thank you!
