What line is the amount that shows my adv ctc from my 2020 tax return

Answered on your prior post for the same subject here - https://ttlc.intuit.com/community/retirement/discussion/where-on-what-line-of-my-2020-return-do-i-dind-the-amount-of-advctc/01/2781662#M181875

You asked this same question in another thread.  As explained----there were no advance child tax credit payments in 2020.   The only year that advance child tax credit payments were made was in 2021, from July 2021 to December 2021.   Those payments had to be entered on your 2021 tax return, and then the remaining amount that you could get was on line 28 of your 2021 Form 1040.   

You are asking about tax year 2020-----the amount of the child tax credit for 2020 was $2000.  The child tax credit for 2020 was shown on line 19; the refundable additional child tax credit amount was shown on line 28 of the 2020 Form 1040.
