I still haven’t received my state income tax return deposit. What do I do?

You first need to be sure it was successfully filed.  Here's how:

If you efiled, be sure your efiled state return was accepted.  If you used Online TurboTax, you can check by looking in your Online account.  At at the Tax Home scroll down the page to "Your Tax Returns & Documents."   Expand that section and choose tax year 2019.   What does it say for the state return--does it say accepted, rejected, printed, started, ready to mail, or what?

Or did you choose to file by mail instead?  TurboTax does not mail it for you.  If you chose that method, you have to print, sign, date, and mail it.   There have been longer delays this year with mailed returns due to the Coronavirus situation.

The FAQ below tells how to check on a state refund and has a link for your state.
