Other financial discussions

I went back on the IRS portal to check for an update it gave the option to enter his direct deposit information so when I did it wanted me to enter his AGI but his is on SSI and don't file taxes so I put 0 then it gave me the option to choose either receive a refund or owe money and I can't choose either one because he is on SSI and he never files taxes. So it won't let me go pass the page without choosing an option so I'm trying to figure out will he still receive his stimulus check in the mail?
