[California] Should I amend? Forgot to add exercised stock options but the spread is small
I exercised my startup ISO's, however the spread was very small (~$30). Due to the small spread, it didn't trigger AMT for me, so I did not report anything in my tax return because I wasn't aware that I had to. I didn't receive any tax forms regarding this exercise.
I have already submitted my tax returns for 2022, but upon looking back I noticed there is actually a row called "Stock options" to include this (California Adjustments — Residents, Section B, 8k.). My question is, since the amount is so small, should I even amend my return? And if so, do I have to amend both federal and state? Is this considered a part of my income? This would be for the state of California. Thank you!
