I only got 600 for my stimulus payment I need to file 1040. An address change to so I can set up direct deposit for my remaining 1200 I'm owed from last year's stimulus

When you file your 2020 tax year return, you will get credit for the stimulus you did not receive (but were eligible for). The credit will either be subtracted from the tax you owe, or it will increase your refund. 

There is a section in TurboTax that asks what you have received thus far and reports that on your return accordingly.
