Hello and thanks for your help. In 2017, my husband overfunded his 401k by $1850. We reported this on form 1099-R in 2018, Code P in Box 7. Code P indicates that this is a 1099-R for Year 2018. This is the instruction given, even if no 1099-R was actually received. Fast forward to 2019 - we received the 1099-R. Unfortunately, it includes a different amount: $2007.94, which is $1814.74 + Gain of $193.20. It indicates Code 8 in Box 7 - "
Excess contributions plus earnings/excess deferrals (and/or earnings) taxable in 2018." Should I amend the 2017 tax return filing to show $2007.94? Or, can I just include the gain of $193.20 when I file this year for 2018?
