Can someone help me understand why for question 5 of the recovery rebate worksheet, the taxpayer with SSN, who lived in the US entire year will not qualify to claim the rebate if he/she has dependents with no SSN. When I check "No" to this question, all figures disappear. In fact, it says "stop, you cannot take the credit".

My question is does stimulus check 3 require dependents to have SSN for taxpayers who have SSN to qualify to claim the rebate? That is what this question appears to suggest. Taxpayer has SS, but dependents are yet to apply for ITIN and when I answer no to this question, taxpayer loses the rebate. Is this accurate?

Also, spouse just arrived in the US in December, can the rebate be claimed for the spouse?

Any help will be greatly appreciated.
