How to know if the capital gain is from inside or outside the state you are filing tax return for?

I have this question: How to know if the capital gain (for a stock for example) is from inside or outside the state you are filing tax return for?

Thank you!

Under what circumstances would it be from a different state? Did you move? You would look at the dates of the sales and attribute the correct amounts to each state.

Yes we moved in 2020. Thank you for the answer.
