After you file

I did filed my 2018 tax return in 2022 and it got crossed 3 years. I see i lost 4000$ refund . The reason for delay is i was not in this country from 2018 to 2022 because i lost my job and left this country. Other thing is I/My family got screwed up with COVID and spent thousands of dollors to come out of that situation. Is there any possibility if i can ger my refund at this time. Now i am in United states
