I efiled my returns and forgot I had sold some stocks at the very beginning of 2018 that were bought for me when I was born. The sale does not effect my federal return so I wasn't going to amend it to add a schedule D.
My state does not treat LTCG more favorably than standard income, so the money from the sale actually leaves me owing $80. After a little research it seems my state does not have a specific form for LTCG. LTCG are instead accounted for when importing my AGI from line 7 of my 1040.
I wasn't going to amend my federal return because it does not affect my federal tax liability and they have already processed it and given me my refund. However, if I amend my state return with the correct AGI it won't match my filed federal return.
Do you think I need to amend both, or will the state realize where the difference came from? Kicking myself I forgot about that sale, what a pain!
