You can go directly to the W2 to make the entries using these steps.
- Select My Account in the upper right
- Select Tools
- Select Topic Search (see image attached)
- Search for W2 and select GO
- Add another row to report two states on one W2
You cannot reallocate any state withholding because we have to assume the employer paid your state income tax withholding to the state listed on the W2.
File each state return as a part-year resident
