As far as the advanced child tax credit. if you have a 17-year-old that turns 18 before December 31, 2021 then you would receive $500 total for that dependent instead of the larger $3000. 

When will I receive the 500.00?

The Other Dependent tax credit of $500 is included in your federal tax refund.

"As far as the advanced child tax credit. if you have a 17-year-old that turns 18 before December 31, 2021 then you would receive $500 total"  is a misstatement.   Your child is not eligible for any ADVANCED  payment.  That answer just means he is only eligible for the $500 "other dependent" credit, which will not receive until you file your 2021 tax return next year.  He is too old for any child tax credit.
