I just (July 2021) received a corrected 1099-B for 2018. There is one transaction with a prior LT gain of $4.70 (rounded to $5.00) that is now $6.12 (rounded to $6.00). Surely I don't have to file an amended return for 2018 for a LTCG increase of $1.00, do I? That amount shouldn't affect any additional tax due as it would be less than $1.00. Anyone see any issue just ignoring this?
