Form 8812 is for the Advanced Child Tax Credit that was given out to some taxpayers beginning in July 2021. To reconcile this with the IRS, there is a question for everyone to answer as to whether or not you received the Advanced Child Tax Credit. I am assuming since you are filing the 1040 SR you did not receive the Advanced Child Tax Credit. The form will generate based on how you answered the question when you were answering questions.
Form 8812 will remain in the return.
