hello,
today I received a mail from IRS on my tax return for 2020, which stated my child doesn't have the SSN before the due date of tax return.
I filed extension for year 2020, which means my due date is 10/15/2021 and my child got the SSN in Sep 2021, from https://www.irs.gov/publications/p972, in publication p972, the due date included extension, my understanding the due date for 2020 tax return Oct 15 , 2021.
Is my understanding correct ? why IRS reject my child's CTC ? how to communicate with IRS to resolve this issue ?
Thanks
