IRS site says I'm not eligible for the stimulus but I am eligible

Has anyone gotten the message on the IRS site saying they're not eligible but they are using the criteria? My friend is incarcerated and I see no reason why she wouldn't be eligible, but the site says she isn't. I can't figure out what to do for her at this point. Other inmates have received theirs and there's no reason for her to not be eligible. She filed 2019 taxes and I believe 2020. Any ideas? TIA
