My brother is trying to file his 2022 tax return and the irs is asking for his 2021 agi even though he never filed for 2021. There is an agi on the irs website but when he enters it for confirmation it’s rejected for being incorrect. He already tried putting it as 0 and it still rejected his return.If he wanted to file his 2021 tax return would he have to mail it in? Could he still follow the prompts and just print off the finished documents for the 2021 return and submit it?
