Hi you are right, it does not look it calculating it correctly maybe because the space for the social or itin is blank. But in this case I think he should be getting 1800 if he did not receive any of them. Try this: 

Try this: Uncheck Line 2 where it says Yes and input the x on NO.   (it looks the software is assuming the blank space is a valid ss. It should change to 1200 in the amount line. 

Put 0 on Lines 6  and Lines 9 because the dependents will not qualify if they do not have ss. The software will then assume he is the only one who qualifies, so answer the questions 16 and 19 and that should add 1800. 

Remember, if he is  married, the spouse is not considered technically a dependent even if she did not work. it seems to be a MFJ with 4 dependents. The new law will give him the 1200 for payment 1 and 600 for payment 2. (assuming he did not receive them) Remember, the system went crazy with the stimulus payments. I hope this helps.
