This lady, on her Form 1116 schedule B keeps adding tax carry forwards every year. She is now on her 7th year. Must she complete all 10 years or can she start from 0 next year?.....Also (this subject was discussed before). on her 2023 return she made a small math error, which she corrected by letter, enclosing a copy of the corrected form. So far she received 9, 2644c letters, one every 2 months asking for 2 more months....her daughter called the irs and was told her return was ok..the supervisor would be asked to stop the letters....but today she recieved another one......is there no limit to these letters?... Thanks
