If you have already FILED a 2020 return you CANNOT use the NON filers portal ... it would reject.
And last time they had the non filer's portal open thousands of folks who needed to actually file a return ultimately had to MAIL in the real return and wait months and months for them to process... some are still waiting for the 2019 return to be completed. So haste makes waste especially when trying to circumvent the rules.
Next ... as to the advance CTC payments ... worse thing is you miss one of the 6 advance payments and get it on the tax return instead. If you are already eligible you should be getting a notice from the IRS telling you what is happening and if you have to add or remove a dependent then go online to do so here (parts are still not functioning) : https://www.irs.gov/credits-deductions/advance-child-tax-credit-payments-in-2021
The system is not perfect but the IRS is doing the best they can with the limited resources they have to complete the impossible task that CONGRESS put before them. If you want to be mad at someone call your congress person to complain and get the IRS the budget, personnel and equipment they need to do the job. If you did not know congress has been reducing the IRS budget every year for a decade and expecting them to do more with less which is absurd. The IRS brings in the income to run the government so they have slowed down the income collections and increased spending ... does anyone else see the stupidity to this rational ?
