You really only filed two of those returns in 2021----the amended one in February and the 2020 return very recently. Given the backlog, there is nothing unusual about the time frame for processing those returns. Amended returns normally take at least four months and are currently taking considerably longer. Millions of people are waiting for refunds for their 2020 returns---and many are still waiting for refunds from 2019. If there is a hardship, sure, try contacting an advocate----but it may not help much.
