Choose the address which will appear on the return(s), and will be used for correspondence and any refund check.

After entering both your US and Home Address, you should choose which one to appear on your Federal and State tax return. Please be advised that it is important to use the address that expect to be at for at least the next 6 months so that if you receive any Notice from the tax office or your refund check, you will be able to receive these.

If you are unsure of your expected address, you can hold off on the tax filing until you know your address (if you are going to move to a new place for example, but make sure you are filing ahead of the deadline) or put your relative's address, so that there would be someone to receive whatever might be sent to you.
