When you are starting a new 2024 tax return you should be signing onto the account with the same User ID that you used to create the original TurboTax account - https://myturbotax.intuit.com/
Entering your personal information on the 2024 tax return, you will be asked to enter your resident state. This is the state where you resided on 12/31/2024. Further on you will be asked if you lived in any other states. If you did live in any other state in 2024 then you should answer YES to the question and enter the date in 2024 that you moved to your resident state.
This is all asked in the My Info section of the online program and when you first start the 2024 tax return.
