This U.S lady living in Spain, on her U.S tax return 2023 made, what says is a minor error, whiich she corrected by mailing a correction letter to the irs shortly thereafter. Today. she received her fith letter from the irs, asking for another 60 days to obtain the info they need...she does,nt need to do anything right now.....on the 4th letter she called the irs and was told they,d resolve it and that she shouln,t worry, no penalties are considered...but this lady is so worried...5 letters..??..Based on your experience..what should all this mean?
