After you file

I got this notice Jan 27, 2022, I mailed it before end of January. It’s more than 8 weeks, I called IRS to check for status the person that I spoked to said he doesn’t see anything about it since it’s more than 8 weeks he told me to file 1040x and include schedule EIC for 2020. Is anyone have the same situation like me? I never got any mail from the IRS within those 8 weeks until now.
