How do I change capital gains allocation for a partial year return from allocate by date to allocate by residency percentage?

[TracyM]

Two states, California and Massachusetts. When filling out the CA info I had to touch every transaction, but I cannot discover how to go back to redo some (most) of those edits.

To make changes to your allocation:

1. Open your CA return.
2. On the screen Your 2023 California taxes are ready for us to check, scroll down and select Edit next to 
   Income and adjustments.
3. On the screen Income and adjustments, select continue. TurboTax will divide your income between CA and MA 
4. Continue and make the changes.
