Would you also put zero in for the amounts received by taxpayer (since they didn’t receive anything because they were not eligible based on 2019) to receive the credit? I guess you have to make entries in all the boxes so I would have to enter that the taxpayer did not receive the payments. 

I read that after this third stimulus check, the IRS will send payments for any additional amounts owed based on the 2020 tax return to eligible taxpayers who filed before July 15 - so I’m wondering if we should just wait? Ugh - sorry I am just confused.
