I want to submit my federal return and come back to complete my state filing. Do I need to delete the state return I started in order to do that?

No - you don't have to delete the state return you started.  As you go through the interview to file your return, just mark that you are going to mail your return.  That way TurboTax won't include it with the federal e-filing.

If you wish to e-file your state return, you will have to wait until your federal return is accepted.  Then you can go back into TurboTax and e-file your state.

To get back into your return after printing or e-filing, please follow these steps:

1. In TurboTax Online, sign into your account.
2. Select Tax Home in the left menu.
3. Scroll down to Your tax returns & documents.
4. Select 2018, and then select Add a State (you're not actually adding a state, this just gets you into the right menu).
5. Once you're in your return you can navigate around as usual.
