Our investment club began in 1996 and disbanded in 2018. We use IClub software to file our 1065 and K-1s. We have three stocks acquired prior to 2011 when I understand brokers did not have to report cost basis. The 2018 year end broker report reflects $430.46 more in Long Term Capital Gains than our club records. How do I reconcile this variance on the 1065? Thank you.
